| 摘 要： | 主要对减小OFDM系统中的峰值平均值功率比(PAPR)问题进行了研究。利用Golay互补序列和Reed-Muller码的关系,研究了一种把输入信息序列编成Golay互补序列的分组编码算法,并利用该编码算法对一个16子载波的OFDM系统的PAPR特性进行仿真。理论研究和仿真结果均表明,采用该编码方案后的OFDM信号的PAPR不超过3dB。

| Abstract: | The question on reducing the peak-to-average power ratio(PAPR) in the OFDM system is studied in this paper.The block coding algorithm of encoding input information sequence into Golay complementary sequence is studied by utilizing the relation between Golay complementary sequence and Reed-Muller code.The simulation of the PAPR characteristic for a 16-subcarrier OFDM system is processed based on the coding algorithm.The theoretic analysis and simulation result indicate that the PAPR of the OFDM signal after using the coding scheme is less than or equal to 3dB. |
