Review of Various PTS (Partial Transmit Sequence) Techniques of PAPR (Peak to Average Power Ratio) Reduction in MIMO-OFDM
Orthogonal frequency division multiplexing with multiple inputs multiple output system is one of the best solutions for high speed, efficient and high-quality service for next generation wireless communication. MIMO-OFDM offers spatial diversity and increase the system capacity on time variant and frequency selective channels to improve the reliability via diversity gain. MIMO-OFDM is the most important candidate for wireless communication. The main drawback of this MIMO-OFDM is high PAPR which results in signal distortion and power inefficiency in RF section of transmitter. In this paper, the authors will discuss and compare all the Partial Transmit Sequence (PTS) techniques and conclude that why cooperative PTS is much better than PTS technique.
