Survey on reconfigurable fir filter architecture

Abstract

Finite impulse response (FIR) filters play a key role in most of the communication devices. Many methods have employed to improve the reconfigurability and to decrease its complexity. In this paper we will discuss in detail about three different reconfigurable FIR filter architectures. Although all those three FIR filter architectures are reconfigurable but each of them have different complexity based on the way processing elements are implemented. Each of them has its own merits and demerits compared with the other methods.
