为了便于信号发射，提高信道利用率、发射功率效率以及改善通信质量，人们研制出各种通信信号的调制样式。尽管调制样式多种多样，但实质上调制不外乎用调制信号去控制载波的...

这些代码为 对于基本的FPGA使用模块beep进行了例化 在工程 系统级建模时只需要直接调用就好了(The code for the basic FPGA using the module beep instantiated only need to be called directly in the engineering system-level modeling like)

说明：  用FPGA实现CNN算法，实现CNN加速(Realization of CNN Algorithms with FPGA)

说明：  16级流水线型cordic旋转代码以及测试文件，亲测好用(16-stage pipelined cordic rotation code and test files, pro-testing)

crc校验，非常好用，是从Xilinx的IP演化来的(crc脨 拢 脩茅 拢 卢 脟 鲁 拢 潞 脙脫脙 拢 卢 脢脟)
