组合算法 Matlab中有函数nchoosek，它是返回全部可能的给合数，本例是一个个地产生组合(Combination algorithm In Matlab function nchoosek, it is possible to return all composite numbers in a matrix, in this case is a combination of one to generate)

两种算法（LMS和RLS）实现CDMA系统盲多用户检测的仿真。结论验证了在加性高斯白招生信道下、同步DS-CDMA系统中接收机应用这两种盲多用户检测算法抑制多址干扰（MAI: multiple access interference）和码间串扰（ISI: inter symbol interference）的能力,仿真实验与理论推导相吻合。实验与理论都表明,RLS性能好于LMS，而LMS计算量明显小于RLS。(This paper discusses two algorithms (LMS and RLS) to achieve blind multiuser detection CDMA system simulation. Conclusion is verified in the Additive White Gaussian noise channel, the synchronous DS-CDMA system receiver applications both blind multiuser detection algorithm to suppress Multiple Access Interference（MAI）and Inter Symbol Interference (ISI) the ability of simulation is consistent with the theoretical. Both experiment and theory show that, RLS’s Performance is better than LMS, and the LMS ‘s computation was significantly less than RLS. )

利用matlab对去雾后的图片进行评价，主要用于彩色图片信息熵的统计，值得下载(Use matlab for defogging the picture after the uation, mainly for color picture information entropy statistics, worth downloading)

语音前期处理 对采集输入的语音信号进行倒谱分析(Pre-processing of the collected voice input voice signal cepstrum analysis)

此功能会产生这是一个“搁置”的设计为一个单一的IIR双二阶系数。 wierldy不够，这种过滤器的类型是不标准的Matlab的滤波器设计工具箱的一部分。这些是常用的过滤器是创建一个图形均衡器的音频信号处理。(This function will generate the coefficients for a single IIR biquad that is a "shelving" design. Wierldy enough, this filter type is not part of the standard Matlab filter design toolbox. These filters are commonly used is audio signal processing to create a graphic equalizer. )
