Ansi To Ascii and Ascii to Ansi converter

基于MATLAB的随机子空间算法，对唯输出数据进行分析，可以很好地识别出系统的模态参数。(Based on stochastic subspace algorithm based on MATLAB, the only output data for analysis, can be well identified modal parameters of the system.)

语音信号的盲信号分离算法研究与应用的matlab程序代码(Blind signal separation algorithm research and application of speech signal matlab code)

说明：  未编码传输AWGN信道测试 每帧的输入是相同的，（不是每帧都不一样，这样可以大幅降低计算量） 在帧比特足够多的情况下，应该可以保证随机性(AWGN channel is not coded transmission test input of each frame is the same, (not every frame is different, this can significantly reduce the computation) are enough bits in the frame of the case, should be able to guarantee randomness)

计算近似熵、改进的样本熵及优化的模糊熵,均为matlab下编辑的程序，是很好的复杂度指标(approxy entropy, sample entropy and fuzzy entropy matlab code )
