Abstract :
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.
