Abstract :
Orthogonal Frequency Division Multiplexing (OFDM) has been used for many wireless communication systems. However, the main drawback of this method is the high Peak-to-Average Power Ratio (PAPR). Selected Mapping (SLM) is a technique used for solving the high PAPR problem in OFDM systems. In SLM, the original data sequence is multiplied by a set of predetermined phase sequences and multiple signals with different PAPRs are generated. Then, the one with the lowest PAPR is selected for transmission. The SLM method requires sending of some bits as Side Information (SI) for each data block, which is of critical importance to the receiver for decoding. The SI bits cause a decrease in the bandwidth efficiency; furthermore, incorrect SI detection leads to the loss of an entire data block. In this paper, we exhibit a new SLM technique by using a Multiple Recursive Generator (MRG), a method of generating pseudo random sequences, to send data without explicit SI bits. We show that the proposed technique performs very well in terms of the Bit Error Rate (BER), Probability of detection failure (Pdf) and PAPR reduction.
