随记减量法是从结构的随机振动响应信号中提取该结构自由衰减振动信号的一种方法-With the mind Reduction Act(Reduction Act is credited with random vibration response of the structure from the signal to extract the structure of a method-With free decay vibration signals the mind Reduction Act)

实现信号LMS处理，并输出波形，能够实现信号的处理，可用于声音的处理(It can realize signal LMS processing and output waveform. It can realize signal processing and can be used for sound processing.)

说明：  时间序列分析中的AR模型的matlab简单实现,一个小例子，适合刚入门者使用。。(Simple implementation of the AR model in time series analysis, a small example, suitable for just beginners)

基于傅立叶变换的ofdm模型信道是高斯信道(OFDM model based on fft transform)

一个OFDM符号128个有效符号，插入128个虚拟子载波 符号率（即有效数据率）fsymbol，而发送速率（需要包括虚拟子载波）2fsymbol 输入的数据需要2倍的发送数据率，以便进行内插，实现位定时跟踪，即4倍fsymbol采样率的调制信号 OFDM symbol Nfft=128 points 一个OFDM符号数据点 Nfft*2 = 256 ， Guard Interval点 ＝Ng*2=64 ( a OFDM symbol 128 effective symbols, insert 128 virtual sub-carrier symbol rate (i.e. valid data rate), and fsymbol sending rate (need to include virtual sub-carrier) 2fsymbol input data need 2 times the sending data rate for interpolation, realize a timing tracking, namely fsymbol sampling rates four times the modulation signal OFDM symbol Nfft = 128 points a OFDM symbol of data points Nfft* 2 = 256, Guard Interval point = Ng* 2 = 64 )
