Abstract

This paper presents design and implementation of a sixteen order efficient FIR filter for wireless communication system. In this work, factored canonical signed digit representation (FCSD) is used in order to reduce the design complexity as compared to canonical signed digit (CSD). We have replaced multiplication operation with add and shift method by representing coefficient in CSD and FCSD format for reducing the complexity of the system. FIR filter has been designed using an equiripple method in MATLAB and further synthesized on Spartan3E XC3S500E target FPGA device. Simulation results show that Symmetric FCSD based FIR filter offers 35.68% less number of slices as compared to the direct form filter structure and 8.355% less number of look up tables (LUT) as compared to CSD based filter.
