Introduction
What is adaptive filter theory?
An adaptive filter is a filter that can adjust its parameters automatically according to some criterion or algorithm. Adaptive filters are widely used in signal processing and communication systems to enhance or extract signals from noisy or distorted environments. Adaptive filters can also adapt to changes in the input signal or the desired output signal, making them more robust and flexible than fixed filters.
Adaptive filter theory is the branch of signal processing that studies the design, analysis, and implementation of adaptive filters. It covers topics such as linear prediction, optimum linear filters, Wiener filters, least mean squares (LMS) algorithms, recursive least squares (RLS) algorithms, Kalman filters, neural networks, fuzzy logic, and more. Adaptive filter theory also explores the applications of adaptive filters in various domains such as noise cancellation, echo suppression, system identification, channel equalization, adaptive antenna arrays, radar systems, speech enhancement, speech recognition, and more.

Main features of the book
Comprehensive coverage of adaptive filter theory
The book covers all the major topics and concepts of adaptive filter theory in depth and detail. It starts with an introduction to the basics of linear prediction and optimum linear filters, such as the autocorrelation method, the covariance method, the normal equations, the orthogonality principle, the Wiener-Hopf equations, and the Levinson-Durbin algorithm. It then moves on to the Wiener filters and LMS algorithms, such as the Wiener solution, the gradient method, the steepest descent method, the LMS algorithm, the convergence analysis, the learning curve, the excess mean square error (EMSE), the misadjustment, the tracking performance, and the stability analysis. It then proceeds to the RLS algorithms and Kalman filters, such as the RLS algorithm, the matrix inversion lemma, the forgetting factor, the initial conditions, the convergence analysis, the tracking performance, the stability analysis, and the Kalman filter. It then explores neural networks and fuzzy logic, such as artificial neural networks (ANNs), feedforward networks, backpropagation learning, radial basis function (RBF) networks, recurrent networks, fuzzy sets and systems, fuzzy inference systems (FISs), adaptive neuro-fuzzy inference systems (ANFISs), and hybrid learning algorithms.
Linear prediction and optimum linear filters
Linear prediction is a technique that uses past values of a signal to predict its future values. It can be used to model or estimate signals that have some degree of correlation or structure. Optimum linear filters are filters that minimize some measure of error or distortion between an input signal and a desired output signal. They can be used to enhance or extract signals that are corrupted by noise or interference.
The book introduces linear prediction and optimum linear filters in Chapter 2. It explains how to formulate linear prediction problems using different methods such as the autocorrelation method and the covariance method. It also explains how to solve linear prediction problems using different techniques such as normal equations and Levinson-Durbin algorithm. It also explains how to derive optimum linear filters using different principles such as orthogonality principle and Wiener-Hopf equations.
Wiener filters and LMS algorithms
Wiener filters are optimum linear filters that minimize the mean square error (MSE) between an input signal and a desired output signal. They can be used to enhance or extract signals that are corrupted by additive noise or interference. LMS algorithms are adaptive algorithms that adjust the parameters of a filter iteratively based on a gradient descent method. They can be used to implement Wiener filters when the statistics of the input signal or the desired output signal are unknown or time-varying.
The book covers Wiener filters and LMS algorithms in Chapter 3. It explains how to obtain Wiener filters using different methods such as Wiener solution and gradient method. It also explains how to implement Wiener filters using different techniques such as steepest descent method and LMS algorithm. It also explains how to analyze Wiener filters and LMS algorithms using different criteria such as convergence analysis and learning curve.
RLS algorithms and Kalman filters
RLS algorithms are adaptive algorithms that adjust the parameters of a filter recursively based on a matrix inversion lemma. They can be used to implement Wiener filters with faster convergence rate and lower steady-state error than LMS algorithms. Kalman filters are recursive estimators that use a state-space model of a system to estimate its state variables based on noisy measurements. They can be used to implement RLS algorithms with optimal performance under Gaussian assumptions.
The book discusses RLS algorithms and Kalman filters in Chapter 4. It explains how to derive RLS algorithms using different methods such as matrix inversion lemma It also explains how to implement RLS algorithms using different techniques such as initial conditions and convergence analysis. It also explains how to relate RLS algorithms and Kalman filters using different concepts such as state-space model and optimal estimation.
Neural networks and fuzzy logic
Neural networks are computational models that mimic the structure and function of biological neural systems. They can be used to implement adaptive filters with nonlinear and complex characteristics. Fuzzy logic is a form of logic that deals with uncertainty and imprecision. It can be used to implement adaptive filters with human-like reasoning and decision making.
The book explores neural networks and fuzzy logic in Chapter 5. It explains how to design neural networks using different architectures such as feedforward networks and recurrent networks. It also explains how to train neural networks using different algorithms such as backpropagation learning and radial basis function (RBF) networks. It also explains how to apply fuzzy logic using different systems such as fuzzy sets and systems and fuzzy inference systems (FISs).

Practical applications of adaptive filters
The book illustrates the practical applications of adaptive filters in various domains in Chapter 6. It explains how to use adaptive filters for noise cancellation and echo suppression, such as in headphones, telephones, and hearing aids. It also explains how to use adaptive filters for system identification and channel equalization, such as in modems, wireless communications, and digital subscriber lines (DSLs). It also explains how to use adaptive filters for adaptive antenna arrays and radar systems, such as in smart antennas, beamforming, and direction finding. It also explains how to use adaptive filters for speech enhancement and recognition, such as in speech coding, speech synthesis, and speech recognition.
Noise cancellation and echo suppression
Noise cancellation is a technique that uses an adaptive filter to generate an anti-noise signal that cancels out the unwanted noise signal from the input signal. Echo suppression is a technique that uses an adaptive filter to remove the echo signal that is caused by the reflection or feedback of the input signal. Both techniques can be used to improve the quality and intelligibility of audio signals in noisy or reverberant environments.
The book demonstrates noise cancellation and echo suppression in Section 6.1. It shows how to use an adaptive filter to cancel out the noise from a sinusoidal signal using LMS algorithm. It also shows how to use an adaptive filter to suppress the echo from a speech signal using RLS algorithm. It also shows how to compare the performance of different adaptive algorithms for noise cancellation and echo suppression using MSE criterion.
System identification and channel equalization
System identification is a technique that uses an adaptive filter to estimate the impulse response or transfer function of an unknown system based on its input and output signals. Channel equalization is a technique that uses an adaptive filter to compensate for the distortion or interference caused by a communication channel on a transmitted signal. Both techniques can be used to enhance or recover signals that are corrupted by noise or interference in communication systems.
The book presents system identification and channel equalization in Section 6.2. It shows how to use an adaptive filter to identify the impulse response of an unknown system using LMS algorithm. It also shows how to use an adaptive filter to equalize a communication channel using RLS algorithm. It also shows how to compare the performance of different adaptive algorithms for system identification and channel equalization using bit error rate (BER) criterion.
Adaptive antenna arrays and radar systems
Adaptive antenna arrays are arrays of antennas that can adjust their radiation patterns dynamically based on some criterion or algorithm. Radar systems are systems that use electromagnetic waves to detect or track objects or targets. Both techniques can use adaptive filters to enhance or extract signals from noisy or cluttered environments.
The book discusses adaptive antenna arrays and radar systems in Section 6.3. It shows how to use an adaptive filter to steer the beam of an antenna array using LMS algorithm. It also shows how to use an adaptive filter to suppress the interference from a jammer using RLS algorithm. It also shows how to compare the performance of different adaptive algorithms for adaptive antenna arrays and radar systems using signal-to-interference-plus-noise ratio (SINR) criterion.
Speech enhancement and recognition
Speech enhancement is a technique that uses an adaptive filter to improve the quality or intelligibility of speech signals in noisy or distorted environments. Speech recognition is a technique that uses an adaptive filter to identify or transcribe speech signals into text or commands. Both techniques can use adaptive filters to enhance or extract speech signals from noisy or distorted environments.
The book explores speech enhancement and recognition in Section 6.4. It shows how to use an adaptive filter to enhance speech signals using Wiener filter. It also shows how to use an adaptive filter to recognize speech signals using neural networks.
