Abstract

OFDM is one of the promising techniques for achieving high downlink capacities in future cellular and wireless networks.The major problem of orthogonal frequency division multiplexing (OFDM) signals is high peak to average power ratio (PAPR) of the transmitted signal. A high PAPR brings disadvantages like an increased complexity of the A/D and D/A converters and reduced efficiency of radio frequency (RF) power amplifier. The high peak of OFDM signal can be reduced by PAPR reduction techniques. In this paper partial transmit sequences (PTS) and iterative flipping schemes are discussed to reduce PAPR and compared with original scheme (without PAPR reduction scheme). Computer Simulations results show that the both schemes achieve PAPR reductions, but the result shows that PTS scheme can offer better PAPR reduction performance than the iterative flipping.
