PAPR Reduction using PTS Technique in OFDM – MIMO System

Abstract: In the advancement of technology multicarrier transmission is of great importance. Orthogonal Frequency Division Multiplexing (OFDM) is a promising multicarrier technology for wireless communications. It facilitates high data rate for communication. The biggest drawback which OFDM encounters is high PAPR. The high PAPR results some interference to the system. This paper analyses the PAPR reduction technique called Partial Time Sequence (PTS) with different sub block and concludes that PTS technique is the most promising technique for PAPR reduction in OFDM system. OFDM � MIMO system with reduced PAPR is the best method for multicarrier transmission with higher data rate.
