Himanshi Shrivastava, Prof. Ashish Verma

Abstract: Wi-Fi Broadband services closely rely upon Orthogonal Frequency division Multiplexing (OFDM) method. OFDM has numerous blessings which makes it appropriate for high speed statistics communications. One of the important risks of OFDM is its excessive peak -to- average energy ratio (PAPR). There are different strategies to overcome this disadvantage. Partial Transmit sequence (PTS) is one in all them. on this paper, a modified model of the iterative flipping set of guidelines has been proposed i. e. modified Flipping PTS (M-PTS) on AWGN, RAYLEIGH and RICIAN channel using different modulation which reduces the general overall performance gap.
