Performance Analysis of Peak to Average Power Ratio (PAPR) Reduction Techniques in OFDM System for Different Modulation Schemes
With the increasing demand for high power efficiency, robustness to multipath delay spread and high transmission speed, OFDM has become one of the most promising techniques for next generation wireless communication systems. However, high peak to average power ratio is a major limitation of OFDM system which makes the overall system less effective. Various methods are proposed by the researchers to reduce high PAPR. In this paper, we review and analyze clipping and filtering, exponential companding (EC), selected mapping (SLM) and partial transmit sequence (PTS) techniques and make a comparison among them to identify the best solution for reducing PAPR. Moreover, we change different modulation schemes such as QPSK, BPSK and 16 QAM to observe the effect of modulation on the PAPR reduction techniques.
