Abstract

Selected mapping (SLM) is a technique for reducing the high peak-to-average power ratio (PAPR) in which a suitable signal is selected among a set of alternative signals which all indicate alike information. The chief drawback existing in this method is that transmitter is compelled to send several additional bits called side information (SI) for each data block in order that recovering at the receiver side can be possible. In this paper, we present a novel SLM scheme by using the linear feedback shift register circuit and m-sequence named MSLM technique by which any side information bit is not explicitly sent. In MSLM, The basic idea is to fit the side information into transmitted symbols based upon which some special locations in the transmitted data block are expanded, i.e. some transmitted symbols are extended. In the receiver side, by using some properties of m-sequence the SI bits can be detected. We present the example of our method for an OFDM system through the use of 16-QAM modulation and different m-sequences and finally, concerned results are illustrated from the view point of bit error rate, probability of detection failure and PAPR reduction.
