应用OFDM可以有效地对抗多径时延扩展。循环前缀不仅可以消除符号间干扰（ISI），还能消除子载波间干扰（ICI).本项目完整地仿真了OFDM系统。(Application of OFDM can effectively combat multipath delay spread. Cyclic prefix can not only eliminate inter-symbol interference (ISI), can eliminate Inter-carrier interference (ICI). This project a complete simulation of the OFDM system.)

粒子群算法OptSwarm记录每个粒子的历史最优解（粒子历史最好的适应度）以及全部粒子搜索到的全局最优解。用Wg代表全局最优解，W.,1代表每个粒子的历史最优解。粒子群初始化阶段表OptSwarm的前N行与表ParSwarm中的相同，而Wg的值为表ParSwarm中适应度值的最大值对应的行。(Particle swarm algorithm OptSwarm record the history of each particle the optimal solution (particles history best fitness), and all the particles of the search to the global optimal solution. Use Wg represents the global optimal solution, w., 1 representative of each particle history to the solution. Particle swarm initial stage OptSwarm table before the line and the table ParSwarm N is same, and the value of the ParSwarm Wg for tables in the maximum fitness value corresponding line. )
