The earliest work on adaptive filters may be traced back to the late 1950s, during which time a number of researchers were working independently on theories and applications of such filters. From this early work, the least-mean-square ð LMSÞ algorithm emerged as a simple, yet effective, algorithm for the design of adaptive transverse (tapped-delay-line) filters.
