On the performance analysis of Partial Transmit Sequence using modified flipping algorithm for PAPR reduction in OFDM systems

Abstract

Wireless Broadband services heavily rely on Orthogonal Frequency Division Multiplexing (OFDM) technique. OFDM has several advantages which makes it suitable for high speed data communications. One of the major drawback of OFDM is its high peak-to-average power ratio (PAPR). There are several methods to overcome this drawback. Partial Transmit Sequence (PTS) is one of them. In this paper, a modified version of the iterative flipping algorithm has been proposed i.e. modified flipping PTS (M-PTS), which reduces the performance gap between the iterative flipping algorithm (I-PTS) and the conventional PTS technique. In the proposed algorithm, performance analysis has been done with considering performance/ complexity trade-off.
