摘要

针对减小正交频分复用（OFDM）系统峰均功率比（PAPR）的常规选择性映射（SLM）法不仅运算量大

而且需要传送代表相位序列的边信息

因而降低了有效的传输效率的问题

提出了一种基于线性分组码的Coded-SLM算法。理论分析和计算机仿真都表明

该方法与常规SLM法相比虽然在降低PAPR方面稍微逊色

但与原始OFDM相比能有效地降低OFDM信号的PAPR

而且传输效率和可靠性大为提高。

Abstract

As large amount of computations are not only needed when the conventional Selected Mapping（SLM） technique is used for reducing OFDM system PAPR

but also the effective transmission efficiency is reduced because it is necessary to transmit the side information representing the phase sequence

we propose a linear block code-based coded-SLM algorithm both theoretical analysis and computer simulations show that although slightly poorer in reducing PAPR than the conventional SLM method

this algorithm can reduce the OFDM signal PAPR more effectively than the original OFDM technique and the transmission efficiency and reliability are also significantly improved.
