Implementation of Fixed-Point LMS Adaptive Filter with Efficient Area-Power-Delay
D. Senthilraja | K. Kalaiselvi [3]
Abstract: In this paper, we present an efficient architecture for the implementation of a delayed least mean square Adaptive filter. For achieving lower adaptation-delay and area-delay-power, we use a novel partial product generator and propose an optimized balanced pipelining across the time-consuming combinational blocks of the structure. We propose an efficient fixed-point implementation scheme in the proposed architecture. We present here the optimization of design to reduce the number of pipeline delays along with the area, sampling period, and energy consumption. The proposed design is found to be more efficient in terms of the power-delay product (PDP) and energy-delay product (EDP) compared to the existing structures.
