FFT-based FIR Filter is a unit to perform the finite impulse responce filter based on the Fast Fourier Transform (FFT). It performs the convolution of the unlimited signal sequence with the synthesized impulse responce of the length of Ni=N/2 samples

多相滤波系统的设计与实现，有MATLAB仿真程序，有sysgen的系统仿真，还有VHDL代码，其中还有FIR的系数参数-Polyphase filter system, the design and implementation includes a MATLAB simulation program, sysgen system simulation, and VHDL code, including FIR coefficient parameters, and so on
