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...
متن کاملAn Improved SLM Technique For PAPR Reduction In OFDM Systems
Orthogonal Frequency Division Multiplexing (OFDM) is widely used as a standard modulation for various high data rate wireless communication systems. It is worked by converting high data rate streams into a number of parallel low data rate streams. OFDM has many advantages over single carrier modulation systems. Some of these advantages are robustness to frequency fading channels, high transmiss...
متن کاملAn Improved DSI-PTS for PAPR Reduction of OFDM System
Peak-toaverage power ratio (PAPR) is one of the major problems of orthogonal frequency division multiplexing (OFDM). The larger PAPR signal may cause high out-of-band radiation, when the OFDM signal is passed through a radio frequency power amplifier. In literatures, many researchers proposed various methods to reduce PAPR. Among those, Dummy sequence Insertion (DSI) and partial transmit sequen...
