利用三电平中心削波自相关法实现清、浊音判定，并提取一段话音的基频参数，绘制基频曲线，并将该参数曲线合并到前面提取的短时过零率和短时能量参数曲线图中(Using a three-level center clipping from the relevant law to achieve clear, voiced determination, and extract some of the fundamental parameters of the voice, drawing the fundamental frequency curve and merge the parametric curve to the front of the extraction rate and the short-term zero short-term energy parameters graph)

改程序对一个信号分别进行BPSK、PCM、PM三种处理。(Change procedures for a signal, respectively, BPSK, PCM, PM, three kinds of processing.)

该程序是基于matlab来求lyapunov指数，用该程序可得到lyapunov指数随一变量变化的情况。便于观察混沌与超混沌。(The program is based on matlab to seek lyapunov exponent lyapunov exponent with a variable changes, the program can be obtained. Easy to observe the chaos and hyperchaos.)

Dynamic Programming improvement code

8ASK系统仿真，包括调制和解调。相干解调和非相干解调(8ASK system simulation, including the modulation and demodulation. Coherent detection and non-coherent demodulation)

) Compression using huffman code -with a number of bits k per code word -provide huffman table Huffman coding is optimal for a symbol-by-symbol coding with a known input probability distribution.This technique uses a variable-length code table for encoding a source symbol. The table is derived in a particular way based on the estimated probability of occurrence for each possible value of the source symbol .Huffman coding uses a specific method for representing each symbol, resulting in a prefix code that expresses the most common characters using shorter strings of bits than those used for less common source symbols.The Huffman coding is a procedure to generate a binary code tree.
