在这个分支中，主要是对标准粒子群算法的惯性因子、收敛因子（约束因子）、“认知”部分的c1，“社会”部分的c2进行变化与调节，希望获得好的效果。(In this branch, mainly to the standard particle swarm algorithm of inertial factor, convergence factor (constraints), "cognitive" part of c1, "social" part of the c2 changes and adjustment, hope to get good results.)

作为一个有吸引力的技术， 减轻多径干扰的正交频 分复用（OFDM）已经被广泛应用 在各种广播系统，诸如数字 视频广播（DVB）系统。尽管它的竞争力 属性，OFDM信号的特点是非常高的 峰值对平均功率比（PAPR）的水平。( As an attractive technique in mitigating the multipath interference, Orthogonal Frequency Division Multiplexing (OFDM) has been widely applied in various broadcasting systems such as, the Digital Video Broadcasting (DVB) systems. Despite its competitive attributes, OFDM signals are characterized by very high Peak-to-Average Power Ratio (PAPR) levels.)
