Abstract：Noise frequency modulation(FM)jamming。which belongs to blanket jamming。is already become the main form ofnoise jamming at present。because the wideband was gained by it．Tne spectnlnl ofnoise FM jamming is analyzed by time domain autocorre

这是一个非常完整的qpsk调制解调用fpga实现的工程，在工程中已经能够正常使用，使用的quartus ii 开发，使用Verilog语言，文件中还包含了各种滤波器的系数文件，还有matlab仿真文件，整个工程包含从串并变换，相位映射，到成型滤波，中通滤波，cic滤波，调制，再到解调过成的下变频，匹配滤波，载波提取，位定时，判决，整个完整的过程(This is a very complete QPSK modulation and demodulation using FPGA implemen
