接收机测试输入信号，
生成正余弦波，采样率、频率、幅度、相位可调节
并将生成的数据进行输出
压缩包包括Verilog代码、testbench代码、word文档
matlab仿真代码(The receiver tests the input signal,
Generation of positive cosine wave, sampling rate, frequency, amplitude, phase can be adjusted
And output the generated data
The compressed package includes the Verilog code, the testbench code
Matlab simulation code)
