Survey on Different Architectures of DLMS Adaptive Filter

Rohita P. Patil, Prajakta P. Bharadkar

The LMS Adaptive filter has wide range of applications but it cannot support pipelined operations because of its recursive behaviour. An efficient architecture of Delayed LMS algorithm thus has been proposed that supports pipelining. The paper discuses about the DLMS algorithm and different architectures of DLMS adaptive filter in brief. These architectures concentrates on increasing usable frequency, minimize the adaption delay and area. The comparison between these various architectures based on critical path, hardware elements required is discussed.
