说明：  运行主函数qam.m，可得到调用理论误符号率曲线和仿真结果。仿真结果包括误符号率和误码率。(running qam.m main function will receive the symbols mistakenly called theoretical curve and simulation results. Simulation results include misuse of the symbol rate and bit error rate.)

基本蚁群算法，主要做的是最短路径，请大家修改后应用(Basic ant colony algorithm, the main job of the shortest path, let us apply the modified)

上次上载lp01模的计算，这次将Lp02-06一起上传，对研究光纤特别是光子晶体光纤的都有用哦(last lp01 die on the calculation that this will Lp02-06 together uploads Research on optical fiber, especially photonic crystal fibers have used oh)

基于能量检测算法的认知无线电频谱检测技术研究roc源程序，很实用的。(enegry detection)

The DSI method is basically a modified SLM method. The additional aspect of the DSI method is to add M-bits dummy sequences to the original sequence in order to reduce the PAPR. Where, the dummy bits are inserted at the end of the data sequence (y). Next, after IFFT, we select the M-DSI sequence having the lowest PAPR.
