| 摘 要： | 部分传输序列(PTS)是一种复杂度较高的减小正交频分复用(OFDM)系统峰均功率比(PAPR)的方法。文中介绍了两种降低PTS复杂度的方法,一种是m序列PTS,另一种是迭代移位线性搜索法PTS。并将这两种方法应用到基于IEEE802.16a的OFDM系统中,仿真表明这两种方法都能够降低PTS的复杂度,同时减小系统的PAPR。

| Abstract: | Partial transmit sequences(PTS) is a method with high complexity to reduce the Peak-to-average power ratio(PAPR) of orthogonal frequency division multiplexing(OFDM) system. This paper introduces two methods to reduce complexity of PTS in OFDM system-m-sequence PTS and Iterative-shifting linear searching PTS. The simulations of OFDM system based IEEE 802.16a standard indicate that they can effectively reduce the complexity of PTS and bring sub-optimum performance of the PAPR distribution. |
