OFDMxitongjiangdifengpingbiyanjiu
正交频分复用(OFDM)技术是一种可以有效对抗符号间干扰(ISI)的高速数据传输技术。OFDM是一种特殊的多载波调制方式,它的基本思想是将高速传输的数据流通过串/并转换,变成在若干个正交的窄带子信道上并行传输的低速数据流。OFDM接收机有三个关键技术:信道估计技术,降低峰均比(PAPR)技术和同步技术。OFDM技术能有效的对抗多径衰落等,有着诸多的优点,但是OFDM有一个发展瓶颈,即OFDM信号的峰均功率比很大,很容易导致OFDM信号的交调失真和系统性能的下降。因而如何降低OFDM信号的峰均功率比一直是OFDM技术的一个研究热点问题。论文针对上述问题,重点研究了降低OFDM信号的峰均功率比的SLM与PTS算法,并利用Matlab对算法进行了仿真研究,并对仿真结果进行了分析。(Orthogonal frequency division multiplexing (OFDM) is a high-speed data transmission technology that can effectively combat inter-symbol interference (ISI). OFDM is a special multi-carrier modulation method, its basic idea is to high-speed transmission of data stream through the serial/parallel conversion, in a number of orthogonal narrowband sub-channel parallel transmission of low-speed data stream. OFDM receivers have three key technologies: channel estimation techniques, reduced peak-to-average ratio (PAPR) techniques and synchronization techniques. OFDM technology can effectively combat multipath fading, etc., there are many advantages, but OFDM has a bottleneck in development, that is, OFDM signal peak power ratio is large, it is easy to lead to OFDM signal intermodulation distortion and system performance degradation. Therefore, how to reduce the peak-to-average power ratio of OFDM signal has been a hot topic in OFDM technology. In this paper, the SLM and PTS algorithms for reduc)
