hamming_encodeadecode
用Verilog语言编写的对m序列进行汉明码编译码的程序。具体实现为产生m序列后对其进行(7,4)汉明码编码并加错，然后将其纠错译码并输出，详细过程见仿真。(Written by Verilog m sequence of procedures for coding and decoding Hamming codes. Concrete realization of m sequence to produce its (7,4) hamming code and a mistake, and then error correction decoding and output, see the detailed process simulation.)

dds_test
直接数字式频率合成器DDS设计、Verilog。
产生的信号可以是正弦波或方波、三角波、锯齿波等，自选。
采用DDS技术，将所需生成的波形写入ROM中，按照相位累加原理合成任意波形。
此方案得到的波形稳定，精度高，产生波形频率范围大，容易产生高频。
本实验在设计的模块中，包含以下功能：
（1）通过 freq 信号输入需要的频率的值；
（2）通过 wave_sel 信号选择所需的波形；
（3）通过 amp_adj 信号选择波形放大的倍数。(DDS design of direct digital frequency synthesizer, Verilog.
The generated signal can be sinusoidal or square wave, triangular wave, sawtooth wave and so on, optional.
By using DDS technology, the required waveforms are written into ROM, and arbitrary waveforms are synthesized according to the principle of phase accumulation.
The waveform obtained by this scheme is stable, accurate and easy to generate high frequency waveform.
This experiment includes the following functions in the designed module:
(1) Input the required frequency value through freq signal;
(2) Choosing the required waveform by wave_sel signal;
(3) Select the multiplier of waveform amplification by amp_adj signal.)

add_noisem
把指定的噪声叠加到信号上去.有标准噪声库NOISEX-92，其中带有白噪声、办公室噪声、工厂噪声、汽车噪声、坦克噪声等等，在信号处理中往往需要把库中的噪声叠加到信号中去，而噪声的采样频率与纯信号的采样频率往往不一致，需要采样频率的校准。
(The specified noise superimposed to the signal up. Standard noise library NOISEX-92, with white noise, office noise, factory noise, car noise, tank noise in the signal processing often requires noise to be superimposed in the library The signal to noise of the sampling frequency and pure signal sampling frequency is often inconsistent sampling frequency of calibration.)
