Orthogonal Frequency Division Multiplexing (OFDM) is a extremely useful and one of the most widely used wireless technology. Its high spectral efficiency, low inter symbol interference and very less cross talk makes it highly used in TV broadcasting or wire line systems like Asymmetric Digital Subscriber Line (ADSL). The increasingly useful OFDM systems to suffer from one major disadvantage of having a high PAPR, which is due to the superposition of N sub carriers. In this paper, the authors counter the high Peak to Average Power Ratio (PAPR) using Partial Transmit Sequence (PTS) algorithm, which is a more efficient technique than some other PAPR reducing techniques like selected mapping, clipping and amplitude filtering.
