使用matlab查询日期的方法，有需要的看看。(The date of the use of matlab query methods, there is a need to look at.)

利用matlab编写的m序列发生器。内容参见《FPGA设计及应用》褚振勇编 西安电子科技大学出版社(Matlab prepared using m sequence generator. See the contents of )

OFDM系统仿真，包含了发射、信道估计、接受等完整的OFDM系统仿真(his simulation script set allows for an OFDM transmission to be simulated. Imagetx.m generates the OFDM signal, saving it as a windows WAV file. This allows the OFDM signal to be played out a sound card and recorded back. Imagerx.m decodes the WAV to extract the data. settings.m contains all the common settings to specify all the simulation parameters such as FFT size, number of carriers, input data source file, input and output WAV files, etc. See settings.m for more details. )
