说明：  大量遗传算法实现程序，用ＭＡＴＬＡＢ实现．借花献拂！(large amounts of genetic algorithm procedures, using MATLAB. Presented by fu spent!)

基于遗传算法的多目标优化的例子，是工具箱中的的例子(based on genetic algorithms multi-objective optimization example, the toolkit is an example)

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.)
