一篇关于MATLAB的基础知识，供大家使用，希望对大家有用，(A basic knowledge of MATLAB for everyone to use, we want to be useful,)

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 (128 of an OFDM symbol of a valid symbol 128 inserted virtual sub-carrier Symbol rate (the effective data rate) fsymbol sending rate (including virtual subcarriers) 2fsymbol Of the input data needs to be 2 times the transmission data rate, in order to carry out the interpolation, to achieve the bit timing tracking, i.e. four times the sampling rate modulation signal fsymbol OFDM symbol Nfft = 128 points One OFDM symbol data points nfft* 2 = 256, the Guard Interval dot = Ng* 2 = 64)

信号用m序列进行扩频，成型滤波和BPSK调制后经过信道发送到接收端，接收端进行解扩解调(Using m sequence spread spectrum signal, after forming filter and BPSK modulation channel is sent to the receiver, the receiver to enlarge demodulation )
