正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)信号具有较高的峰均功率比(Peak to Average Power Ratio,PAPR),不仅影响功率放大器(High Power Amplifier,HPA)的工作效率,而且HPA使得OFDM信号产生严重的非线性失真,...
为了降低正交频分复用(orthogonal frequency division multiplexing,OFDM)信号的峰均功率比(peak to average power ratio,PAPR),提高系统的误比特率(bit error rate,BER)性能,提出了一种结合时域信号分割和部分子块循环移位的低复杂...

In this paper,a novel genetic algorithm assisted partial transmit sequence(NGA-PTS)is proposed to reduce the peak-to-average power ratio(PAPR)of orthogonal frequency division multiplexing(OFDM).However,the searc...
