USE OF PEAK-TO-AVERAGE POWER RATIO IN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING TECHNIQUES: A REVIEW OF THE DRAWBACKS

摘要

The goal of this study is to provide readers knowledge of high. peak-to-average. power ratio. (PAPR) that is the bottleneck of the orthogonal frequency division multiplexing (OFDM) system. This study also highlights the drawback of the PAPR reduction techniques and each of which are explain briefly. This review starts with an illustration of the OFDM system and PARR. Introduction of several techniques that can be classified into three parts (distortion signal, scrambling signal, and coding) for compacting the above-mentioned problem of high peak which is the objective of this study. Further in this paper most of PAPR lessen techniques are elaborated with their drawbacks which illustrated in detail. Each technique reduced the high output of power envelope fluctuation but at the expense of reduced data rate, greater transmission of signal strength, increased system intricacy and regression the performance bit-error-rate (BER).
