Design of the Poly-phase FIR Filter Based on FPGA

The finit impulse response filter (FIR) is used massively in each kind of digital communication system,realizes each kind of function.The function of FIR filter with the field-programmable gate array obtains the universal application.This paper uses the FPGA to realize the poly-phase structure of the filter,which can save the resources of FPGA,reduces the calculation.
