It plots the BER vs SNR for PSK and QAM

说明：  利用IIR滤波器设计一个低通滤波器，能够分析到电力系统中的三次谐波，要求满足如下指标：截止频率150HZ，阻带衰减≥30db(IIR filter design using a low-pass filter, to analyze the power system in the third harmonic, the requirements to meet the following indicators: cut-off frequency 150HZ, stopband attenuation ≥ 30db)

说明：  RLS算法多麦克风语音降噪.rar 最小二乘自适应滤波 里面包括文档等(RLS算法多麦克风语音降噪.rar)

说明：  指纹识别例子和源代码，对于模式识别、人工智能研究者有一定帮助(Fingerprint identification example and source code, for pattern recognition, artificial intelligence researchers have help )

频谱分析实践，将信号源发出的信号强度按频率顺序展开，使其成为频率的函数，并考察变化规律，称为频谱分析。研究噪声的频谱是为了深入了解噪声源的特性帮助寻找主要的噪声污染源，为噪声控制提供依据，为噪声控制提供依据。(Spectrum analysis practice, the signal strength of the signal source frequency in order to start by making it a function of frequency, and variation study, known as spectrum analysis. Of the noise spectrum is to understand the characteristics of noise sources to help find the major noise sources, provide the basis for the noise control, provide the basis for the noise control.)

说明：  运用matlab求矢量x的均值和方差。代码实现简单，运行正确(Using matlab find the mean and variance of the vector x. Code is simple, right)
