摘要
针对OFDM峰均功率比(PAPR)问题,提出利用Golay互补序列(GCS)降低16QAM-OFDM信号PAPR的方法,分析了其PAPR最大值、16QAM序列集合大小以及编码率,讨论了编译码算法和纠错能力。研究结果表明,这些降低PAPR的方法在系统设计有不同要求时具有不同先决应用条件。
Focusing on the problem of the peak-to-average power ratio （PAPR） of OFDM technique, the methods for reducing the PAPR of 16QAM-OFDM signal using Golay complementary sequence （GCS） are investigated, their properties, namely the maximum PAPR value, set size of 16QAM sequences and code rate, are analyzed and compared in detail, and the encoding and decoding algorithms and error control capabilities are discussed in brief. Analysis results suggest that these methods have different predetermined application conditions for different system design requirements.
