Performance Evaluation of Different Companding Techniques for Peak-to-Average Power Reduction of an OFDM Signal

Orthogonal frequency division multiplexing (OFDM) system is widely used wireless communication system in recent years. The major drawback of OFDM system is high Peak-to Average Power Ratio (PAPR). To reduce the PAPR of OFDM system different PAPR reduction techniques have been proposed. In this paper, we are evaluating the performance of different non-linear companding techniques.
