| 摘 要： | OFDM系统的一个主要缺点是峰均功率比(PAPR,Peak-to-Average Power Ratio)过高。部分传输序列(PTS,Partial Transmit Sequence)是一种复杂度较高的降低PAPR的方法。本文介绍一种以m序列代替辅助信息的次最优PTS方法,通过基于IEEE 802.16a的OFDM系统平台仿真,结果表明这种方法降低了系统的复杂度,同时有效减小了系统的PAPR。

| Abstract: | One of the important problems in OFDM system is the high PAPR(Peak - to - Average Power Ratio) . PTS is a method of high complexity to reduce the PAPR of OFDM system. This paper introduces a sub -optimum PTS method,in which m - sequence is utilized instead of side information. The simulations of OFDM system based on IEEE 802.16a which indicates that it can effectively reduce the complexity of PTS and bring sub-optimum performance of the PAPR distribution. |
