OFDM
OFDM,实际上OFDM是MCM Multi-CarrierModulation,多载波调制的一种。其主要思想是:将信道分成若干正交子信道,将高速数据信号转换成并行的低速子数据流,调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开,这样可以减少子信道之间的相互干扰 ICI 。每个子信道上的信号带宽小于信道的相关带宽,因此每个子信道上的可以看成平坦性衰落,从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分,信道均衡变得相对容易。在向B3G/4G演进的过程中,OFDM是关键的技术之一,可以结合分集,时空编码,干扰和信道间干扰抑制以及智能天线技术,最大限度的提高了系统性能。(OFDM)

Chaotic-Particle-Swarm-Optimization
混沌粒子群优化(CPSO, Chaos Particle Swarm Optimization)算法融合了PSO算法的快收敛和CO算法的遍历随机等特点,在PSO算法每一代挑选出的最优解附近的区域里,用混沌算法进一步搜索,防止其陷入局部最优值,从而改进了PSO算法的不足,成为一种高效的优化算法。(Chaotic Particle Swarm Optimization (CPSO, Chaos Particle Swarm Optimization) algorithm combines the features of the PSO algorithm fast convergence and CO traversal algorithm randomly each generation in the PSO algorithm selected area near the optimal solution, further chaos algorithm search prevent it from falling into local optimal value, thus improving the deficiencies of the PSO algorithm, an efficient optimization algorithm.)
