It is a matlab sourcecodes for the calculation of refrective index of AlGaAs alloy. I think it is useful for the guys who need the accurate value of the refrective index. It can be expanded to the other semiconductor alloy if you have the related parameters.

This is a comprehensive book about MATLAB coding for econometric applications. all engineers and economist who concern about econometric, should read it

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.)

说明：  LDPC码编解码程序，LDPC，Matlab，VMSK(LDPC encoding and decoding procedures)
