Selected mapping based PAPR reduction in WiMAX without sending the side information

WiMAX with its standard IEEE 802.16d/e is the advanced technology used for long range communication with high data rate. It is well known that theorthogonal frequency division multiplexing (OFDM) is a promising technique for getting high data rate in multi path fading environment. Hence the physical layer of WiMAX uses OFDM. But the main disadvantage of OFDM is the high peak to average power ratio (PAPR). In this paper we analyze how PAPR reduction is achieved using selected mapping (SLM) technique and simultaneously without sending the side information (SI) along with the OFDM symbol. Here the PAPR performance using complimentary cumulative distribution function (CCDF) plot and the probability of SI detection error performance have been evaluated as the criteria for WiMAX standard IEEE 802.16e.
