摘要

数字波束成形技术是5G通信中的关键技术之一。然而，数字波束成形中过高的峰均比会造成信号发射端功率放大器进入非线性工作区域。针对现阶段概率类方法中的选择性映射类算法带宽利用率低和运算复杂度高的问题，提出一种基于 MUSIC 算法的盲选择性映射方法。该方法不用传输边带信息，就可提高频带的利用率；同时，在运算复杂度和峰均比的抑制效果上，所提方法较选择性映射算法有一定的改善。

Abstract

Digital beam-forming technology is one of the key technologies in 5G communication.However

the high peak-to-average power ratio in digital beam-forming would make the power amplifier work in the nonlinear region.Nowadays

the solutions to the high peak-to-average power ratio

such as selected mapping

embedded side information selected mapping have some faults:the complexity is high

and the utilization of the bandwidth is low.A blind selected mapping method to reduce the high peak-to-average power ratio based on MUSIC algorithm was proposed.In this method

the side information was omitted

so the utilization of the bandwidth was improved.Simultaneously

the result of the peak-to-average power ratio reduction and the complexity is much more enhanced.
