此代码仿真了一个语音输入输出系统，语音信号经过AD转换后，经过DSSS调制解调后，通过DA转换还原输入的声音，每一步的的波形都可以观测，对实际DSSS系统设计有很大的参考价值(This code simulation of a voice input and output systems, speech signal after AD conversion after DSSS modem through DA conversion to restore the input voice, each step of the waveform can be observed, the actual design of DSSS systems have great reference value)

matalb编写的debye函数m文件(prepared matalb Debye function m file)

很有用的源代码，实现的效果很好，很值得收藏，不错平(Useful source code, to achieve good results, it is worth collecting, good level)

原子范数约束谱估计文章，是稀疏恢复领域比较好的文章(Atomic Norm Constraint Spectral Estimation Articles)

matlab下，knn均值算法，可直接调用(matlab under, knn means algorithm, can be called directly)

基于MATLAB和电子表格共同的有限元程序。电子表格进行前处理，MATLAB读入进行计算及后处理。(Based on MATLAB and Spreadsheets a common finite element program. Before dealing with spreadsheets, MATLAB reads the calculation and post-processing.)
