This totally revised and expanded reference/text emphasizes the intricate relationship between adaptive filtering and signal analysis-highlighting the most recent stochastic processes, signal representations and properties, analytical tools, and implementation methods. Includes new chapters on adaptive techniques in communications and rotation based algorithms Providing practical applications in information, estimation, and circuit theories, the Second Edition of Adaptive Digital Filters contains current FORTRAN listings of computer subroutines novel engineering design options and finite word-length effects for least mean squares (LMS) modern linear prediction theory for fast algorithm operations state-of-the-art design and performance aspects for fast least squares (FLS) and more With nearly 1400 display equations and drawings, the Second Edition of Adaptive Digital Filters is an invaluable reference for electrical, electronics, video, audio, network, computer, digital design, multimedia software, signal processing, and communication engineers, and an authoritative text for upper-level undergraduate and graduate students in these disciplines.
