摘要

定向选择映射(dSLM)是多输入多输出(MIMO)正交频分复用(OFDM)系统中一种众所周知的峰均功率比(PAPR)降低方案。本文提出了零强迫(ZF)接收机的dSLM改进方案。本文的贡献是双重的;首先，在保持误码性能的同时，恢复了没有侧信息的传输相位矢量;其次，降低了接收机的复杂度。

Reduced complexity dSLM recovery in MIMO-OFDM without side information

Directed Selected Mapping (dSLM) is a well known Peak-to-Average Power Ratio (PAPR) reduction scheme in Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems. This paper presents a modification to dSLM for a Zero-Forcing (ZF) receiver. The contribution in this paper is twofold; firstly, the transmitted phase vector is recovered without side information whist maintaining bit error performance, and secondly, receiver complexity is reduced.
