چکیده

Orthogonal Frequency Division Multiplexing is considered as one of the prominent technology for 4G communication to achieve high data rate, spectral efficiency over multipath fading channel. However one of the major drawbacks of OFDM system is high PAPR. Repetitive clipping and filtering(RCF) and selective mapping (SLM) techniques being considered as simple and less complex compare to other techniques, both techniques are analysed and simulated result will give significant reduction in PAP ratio.

An Efficient Scheme for PAPR Reduction of OFDM based on Selected Mapping without Side Information

Orthogonal frequency division multiplexing (OFDM) has become a promising method for many wireless communication applications. However, one main drawback of OFDM systems is the high peak-to-average power ratio (PAPR). Selected mapping (SLM) is a well-known technique to decrease the problem of high PAPR in OFDM systems. In this method, transmitter is obliged to send some bits named side informati...
