PAPR reduction through lossy coding

Orthogonal Frequency division multiplexing is the modulation technique used for the fourth generation wireless communication system. In OFDM, Signals can be modulated by multiple carriers. OFDM uses the bandwidth of the spectrum efficiently. But the limitation of the OFDM system is the high Peak to Average Power Ratio (PAPR) which results in the degradation of the signal quality. Hence reducing the PAPR is the major criteria for any systems. Several researchers has proposed and implemented the methods to reduce the Peak to average power ratio. In this paper an attempt has been made to provide an overview of the different PAPR reduction techniques in OFDM and proposes new lossy coding method which can be adopted to reduce the PAPR in the OFDM systems with the introduced BER.
