摘要
正交频分复用技术非常适合高速通信系统,但却存在着高峰均比问题。部分传输序列法因其灵活有效的降低OFDM系统的峰均功率比而被广泛的研究。对以前技术研究之后,提出一种基于相位的搜索算法。仿真结果表明,用这种方法降低系统的计算复杂度,并且其性能和以前的方法相比没有降低。
Orthogonal Frequency-Division Multiplexing （OFDM） system is very good for the high speed communication system,but the high Peak to Average Power Ratio （PAPR） is a very serious problem. Partial Transmit Sequence （PTS） scheme has been widely studied to reduce the high PAPR of OFDM signal since it is flexible and efficient. This paper proposes a new phase search algorithm that reduces the high PAPR. Our simulation results show that the proposed scheme provides significant computational savings while yielding a performance similar to that of the conventional PTS method.
