Abstract:
This paper presents the architectural implementation of adaptive LMS filter, using the suitable algorithms such as DLMS and NLMS. The existing DLMS adaptive filter is modified by using a 4-2 compressor for faster partial product computation which in turn reduces the area utilization and the power consumption. Then the normalized LMS filter is implemented as that of the DLMS filter with compressed error generated in DLMS filter. From the synthesis report it is found that the number of gate counts is reduced by the proposed system and the power consumption of the existing DLMS filter was found to be 90mW and that of the proposed DLMS and NLMS filter is 53mW and 65mW respectively.
