Abstract

This paper proposes a design and adaptive digital filter using Fast Block Least Mean Squares (FBLMS) adaptive algorithm. The filter structure is based on Distributed Arithmetic (DA), which is able to calculate the inner product by shifting, and accumulating of partial products and storing in look-up table, also the desired adaptive digital filter will be multiplier less. Thus a DA based implementation of adaptive filter is highly computational and area efficient. Furthermore, the fundamental building blocks in the DA architecture map well to the architecture of todays Field Programmable Gate Arrays (FPGA). FPGA implementation results conforms that the proposed DA based adaptive filter can implement with significantly smaller area.
