Performance and analysis of PAPR reduction schemes based on improved low complexity four partial transmit sequences and constellation methods

The major drawback of OFDM is the high PAPR which in results, increases the complexity of Analog to Digital (A/D) and Digital to Analog (D/A) converters and also reduces the efficiency of RF High Power Amplifier (HPA). High PAPR values can also lead to serious problems such as severe power penalty at the transmitter, which is not affordable in portable wireless systems where terminals are powered by battery. Here in this letter we proposed analysis of PAPR by using an improved low complexity four partial transmit sequences (ILCF-PTS) and compared with the existing techniques such as original OFDM, selective level mapping (SLM), active constellation extension (ACE) and also with adaptive active constellation extension (AACE). Experimental analysis shown that the IF-PTS scheme is superior to previous PAPR reduction techniques.
