Performance Analysis of High Speed and Area Efficient Finite Impulse Response Filters

Abstract

This study represents the designing and implementation of a bandpass finite impulse response (FIR) filter of order 31 using windowing techniques. The frequency parameters used are of a typical GSM receiver,19 which is one of the applications of software-defined radio (SDR). To minimize filter area, various multiplication techniques like a canonical signed digit, Vedic multiplier, booth multiplier, and modified booth multiplier are used. Adders like ripple carry adder, carry save adder, carry look ahead adder, and Kogge-Stone adder are used to add the product from the multiplier unit. A comparison between three different windows has been made. The FIR is designed in MATLAB using a windowing technique. Then it is synthesized on Xilinx 14.7, Virtex 6 XC6VLX760, whose results are included in this paper.
