Enhanced ACE Scheme for PAPR Reduction in OFDM Systems

Problem Definition

PROBLEM DESCRIPTION: The problem that this research project aims to address is the high Peak-to-Average Power Ratio (PAPR) in Orthogonal Frequency Division Multiplexing (OFDM) systems operating in frequency selective mobile fading channels. High PAPR leads to signal distortion and degradation in the performance of the communication system, resulting in increased Bit Error Rate (BER). Existing PAPR reduction techniques have limitations in effectively reducing PAPR without introducing additional distortion to the signal. Therefore, there is a need to develop an enhanced PAPR reduction scheme that can effectively reduce PAPR while maintaining low BER in frequency selective fading channels. This research project will focus on implementing the ACE scheme with Peak Inversion (PI) and Butterworth band pass filter to address this challenge and improve the overall performance of OFDM systems in mobile fading channels.

Proposed Work

The proposed research project titled "Space-Time Trellis Coded OFDM Systems in Frequency Selective Mobile Fading Channels with PAPR Reduction Scheme" aims to analyze the Bit Error Rate with the Signal to Noise Ratio in wireless communication systems. The research will focus on implementing the ACE scheme with the Peak Inversion (PI) technique and incorporating a Butterworth bandpass filter for improved distortion reduction and signal smoothing. Among various Peak-to-Average Power Ratio (PAPR) reduction techniques, PI has been identified as an effective method for reducing PAPR levels significantly. The analysis will be conducted using MATLAB software to evaluate the performance of the enhanced ACE scheme in terms of both PAPR and BER. This project falls under the Latest Projects and Wireless Research Based Projects categories, with subcategories including MATLAB Projects Software and OFDM based wireless communication.

It is anticipated that the findings of this research will contribute to advancements in wireless communication systems.
