PAPR Reduction Using Hybrid PTS-Companding-SLM Technique in OFDM Communication System

Orthogonal Frequency Division Multiplexing (OFDM) has developed to a popular communication technique for high speed wireless communication in the last decade. Orthogonal Frequency Division Multiplexing (OFDM), is also called Discrete Multi-Tone modulation (DMT). High Peak-to-Average Power Ratio (PAPR) is one of the exigent matters for Orthogonal Frequency Division Multiplexing (OFDM). In this paper, a PAPR reduction technique is proposed which is a combination of Partial Transmit Sequence (PTS), companding and SLM techniques. Simulation results are presented, commented, and compared with the results obtained applying PAPR reduction methods already proposed in literature.
