摘要 OFDM系统的一个主要缺点是峰均功率比过高。部分传输序列是一种复杂度较高的能够降低OFDM系统的峰均功率比的方法。提出一种用迭代移位线性搜索法确定最优辅助信息的次最优PTS方法,通过基于IEEE802.16a标准的OFDM系统平台的仿真,表明这种方法能够很好地解决系统复杂性和降低峰均功率比的问题。 One of the important problems of OFDM systems is the high PAPR. PTS is a method with high system complexity to reduce the PAPR of OFDM systems. This paper proposes a sub-optimization PTS method-Iterative-shifting linear searching method which can be utilized for finding the optimum side information, and the simulations of IEEE 802.16a standard OFDM signals indicate that it can achieve the lower PAPR and complexity of system.
