用MATLAB仿真的滤波器，里面包括一个文档和MATLAB文件，希望对初学者有用！(Filter simulation using MATLAB, which includes a document and MATLAB files, useful for beginners hope!)

直接序列扩频就是直接用具有高码率的扩频码序列在发端去扩展信号的频谱。而在收端，用相同的扩频码序列去进行解扩还原成原始的信息。(Direct Sequence Spread Spectrum is the direct use of the spreading code sequence with a high rate in the originator to expand the spectrum of the signal. Receiving end, using the same spreading code sequence to despread the broadening of the spread spectrum signal to restore the original information.)
