Abstract

This paper addresses the issue of high computational complexity associated with side information (SI) estimation in orthogonal frequency division multiplexing (OFDM) systems that implement selected mapping (SLM) to reduce peak-to- average power ratio (PAPR). The proposed method is based on a slightly modified SLM approach that enables the use of a low complexity binary detection criterion for SI estimation, without the need for SI transmission. Simulations show that the combined PAPR reduction and BER performance of the proposed method is similar to both pilot-assisted Maximum-Likelihood (PAML) SI estimation scheme and standard SLM that presumes perfect knowledge of SI. In addition, relative to the PAML scheme, the proposed method offers significantly reduced computational complexity.
