说明：  昨天刚刚写好的dsb-sc信号生成与解调程序，用离散（dsp）的方法生成DSB信号，载波频率为150khz,音频是500hz和2000hz的混合音，加入SNR=1DB的噪声，用正交解调实现解调，画出解调前后的频谱图，欢迎共同学习，进步。(yesterday just finished the dsb- sc signal generation and demodulation process, discrete (dsp), the signal generated DSB, the carrier frequency of 150kHz, audio is 500Hz and 2000hz mixed audition to join SNR = 1DB of noise, with quadrature demodulator to achieve demodulation, paint around the demodulation spectrum welcome to learn together and progress.)

在做优化的时候，起初选择了GA算法，但是GA的不稳定性（或者陷入局部最优）实在让人抓狂，前后两次的结果相差竟然有时候能达到30 以上，当时由于时间的原因，我只好选择了优化1000次，然后以其中的最小值最为最佳方案。虽然问题也算解决了，但是从学术上将，这种奔方法是让人很尴尬的。所以，我从网上下载了一个GA－PSO算法，试着利用GA和PSO组合的策略进行优化，结果算法很问题，效率和不错。我下载原始算法，有一个问题就是它是针对所有的设计变量上下限都是一样的，所以我对程序进行了修改与改进，现在可以处理上下限不一致的问题，同时fix了一些bug。现在把修改后的程序和大家分享一下，希望能对您有用.注意myfit需要用自己的函数，否则出错，因为我的myfit程序在调用过程中，需要使用matlab的Kriging工具箱 (a optimization method combining GA and PSO)

晶闸管控制串联电阻在500kv电力系统的matlab仿真中的应用。(Modeling and simulation of 500kv power system.The theoretical ground and design realization of alternating current power lines of the new type- Controllable Flexible A.C. Transmission Systems (CFACTS) are considered. Earlier lines of such type had been known as Controlled Self- Compensating High Voltage Transmission Power Lines (CSHVL), as well as Controlled Compact Transmission Power Lines. The CFACTS design principles and the basic CFACTS design directions are implemented. The basic characteristics of CFACTS (500kV) which are studying have great prospects.
