自己做设计用的参数提取程序，主要是LPCC和MFCC。(Designs its own program with the parameter extraction, mainly LPCC and MFCC.)

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.)
