摘要 为降低相干光正交频分复用(CO-OFDM)系统的峰均功率比(PAPR),对序列的实部和虚部分别独立应用部分传输序列(PTS)方法优化处理,并把迭代算法用于计算过程中,得到一种实部和虚部独立迭代优化的PTS方法。理论和仿真表明,该方法在有效减少计算量的同时又能获得较好的PAPR性能。 In order to decrease the PAPR of Coherent Optical Orthogonal Frequency Division Multiplexing（CO-OFDM）system,the PTS method is used to separately optimizing the real part and imaginary part of sequence and the iterative algorithm is applied to the process of the calculation,an improved PTS method which separately and iteratively optimizing the real part and imaginary part of sequence is proposed.It is shown by theory analysis and simulation that this method can improve the PAPR performance and reduce the amount of calculation.
