Abstract: Orthogonal Frequency Division Multiplexing (OFDM) is a form of multicarrier modulation Technique. In this System orthogonally placed subcarriers are used to carry the data from transmitter end to receiver end and has found its way to the high speed wireless and mobile communication world. It has excellent immunity against fading and ISI but its major drawback is peak to average power reduction (PAPR) of the transmitted signal. So many methods are proposed to reduce large PAPR. But most of the techniques are complex. In this paper various optimization technique GA, PSO, Hybrid algorithms are proposed to optimize phase factors in PTS technique of OFDM system. The simulation Results of proposed algorithms are compared with OFDM Results.
Keywords: GA, OFDM, PSO, PTS, PAPR.
