M-Tech Project: Comparative Analysis of PAPR Reduction Techniques in OFDM Systems

Problem Definition

PROBLEM DESCRIPTION: The problem of Peak to Average Power Ratio (PAPR) in Orthogonal Frequency Division Multiplexing (OFDM) systems is a significant issue that causes performance degradation and increased out-of-band power. The high PAPR in OFDM systems leads to reduced system efficiency and reliability, impacting the overall data transmission speed and quality of wireless communication. Various approaches have been proposed for PAPR reduction in OFDM systems, such as Partial Transmit Sequence (PTS) and Selected Mapping (SLM) techniques. However, there is a need to conduct a thorough analysis and comparison of these approaches to determine their effectiveness and performance in reducing PAPR. This M-tech project aims to address the problem of high PAPR in OFDM systems by implementing and analyzing multiple PAPR reduction approaches, specifically PTS and SLM techniques.

By comparing the results obtained from these techniques using MATLAB software, the project seeks to find the most efficient and reliable method for reducing PAPR in OFDM systems, ultimately improving the system performance and data transmission speed in wireless communication applications.

Proposed Work

In the proposed research work titled "An approach to perform analysis of multiple PAPR reduction approaches", the focus is on analyzing Peak to Average Power Ratio (PAPR) reduction techniques in Orthogonal Frequency Division Multiplexing (OFDM) systems. This M-tech level project falls under the wireless projects category and involves the implementation and comparative analysis of two PAPR reduction techniques - Partial Transmit Sequence (PTS) and Selected Mapping (SLM). Both techniques aim to reduce the PAPR in OFDM systems by manipulating the phase factors of sub blocks or generating asymptotically independent OFDM signals to select the one with the lowest PAPR for transmission. The project utilizes modules such as PAPR Reduction using Clipping, Signal Processing, Basic Matlab, OFDM and Wireless Sensor Network. The research is conducted using MATLAB software, and the results and comparisons of the implemented techniques are presented at the conclusion of the project.

This study holds relevance in the field of Digital Signal Processing, particularly in the context of wireless communication research, and contributes to the ongoing efforts to enhance the performance and efficiency of OFDM systems.
