摘要
为有效降低电力线通信正交频分复用系统峰均功率比问题,以最大效率开发利用电力线通信资源,提出了一种改进的基于遗传算法的部分传输序列技术。传统的遗传算法采用二进制编码,计算繁复且占用大量的空间,因此采用一种新的实数编码方法,在实数域上进行遗传运算。仿真结果证明,算法操作简便且收敛效果好。
In order to reduce the Peak to Average Power Ratio(PAPR) of Orthogonal Frequency Division Multiplexing(OFDM) system and develop the resource of Power Line Communication(PLC) effectively, this paper proposes a new Partial Transmit Sequence(PTS) technique based on genetic algorithm. Traditional genetic algorithm?with the binary coding?is?complicated, and?takes?up?a lot of spaces, ?using a new?real-coded?genetic operators?on?the?real number field.?The?simulation results show that?the?algorithm operation?is?simple?convergence effect.
