用于WiMAX的FIR滤波器的研究与FPGA实现

Research and implementation of FIR filter based on FPGA forWimax

文章根据WiMax网络的技术特性,设计了一种可用于数字下变频模块中的高阶FIR滤波器。探讨了实现FIR滤波器的两种算法:分布式算法和乘加算法,比较其优劣。根据实际情况,对分布式算法进行了一定的改进。随后对FIR滤波器进行了Matlab建模,最后用FPGA将其实现,并对结果进行仿真。

Based on the technical characteristics of the WiMax network,I design a digital down-conversion module in order FIR filter.The two FIR filter algorithms： distributed algorithms and multiply-add algorithm,and compare their advantages and disadvantages.Distributed algorithm based on the actual situation,a certain improvement.Matlab modeling,then the FIR filter with FPGA implementation and the results of the simulation.
