| 摘 要： | 针对正交频分复用系统中峰均功率比较大的问题,从分析选择映射法的基本原理和实现框图入手,详细描述了利用线性分组码标准阵列降低OFDM系统PAPR的算法,其核心思想是通过选择陪集中PAPR较小的向量代替选择映射法中的加权向量。最后进行了蒙特卡罗仿真,仿真结果表明,该方法能够明显改善PAPR特性。

| Abstract: | Focused on the problem that the orthogonal frequency division multiplexing system has a large peak-to-average power ratio (PAPR), the basic principle and realization model of selected mapping (SLM) were analyzed, and the algorithm of using standard arrays of linear block codes to reduce the PAPR was proposed. The main idea of the algorithm is to select the vectors of cossets to replace the weighted vectors of SLM. Some results were obtained by Monte Carlo simulations, and it proved that this algorithm has better performance for reducing the PAPR of OFDM signals. |
