The advantages of this technology are a high data rate, high spectral efficiency, and more immunity to <br>interference. However, these advantages are met with disadvantages most important of which is the high Peak to Average <br>Power Ratio (PAPR) of the received signal due to nonlinear components such as power amplifiers) which distorts the signal. <br>Several techniques have been proposed in this paper to reduce PAPR including clipping and filtering, Selective Level Mapping <br>(SLM), and Partial Transmit Sequences (PTS). All simulations are performed on MATLAB program to analyze PAPR <br>reduction and compare reduction techniques with each other.</p> Saddam Hasan Copyright (c) 2024 Elmergib Journal Of Electrical and Electronic Engineering ISSN: 2959-0450 https://ejeee.elmergib.edu.ly/index.php/ejeee/article/view/40 Mon, 27 May 2024 00:00:00 +0000
