Low complexity distributed arithmetic based pipelined vlsi architectures for lms adaptive filters

Abstract

Least mean square LMS algorithm is widely used in system identification channel equalization noise cancellation and several other areas of digital signal processing due to its simplicity and ease of implementation In most of the cases LMS algorithm is not employed directly rather a combination of LMS units in parallel or in series or in block is used to obtain the desired performance For instance the parallel combination of two LMS adaptive filters with different step size has fast con newline newline
