Implet.Fountain Coded PTS Schemes for PAPR Reduction in OFDM System

Orthogonal Frequency Division Multiplexing (OFDM) has emerged as a promising modulation technique for high-speed data transmission in modern wireless communication systems. However the presence of high Peak-to-Average Power Ratio (PAPR) remains a significant challenge in OFDM systems leading to inefficient power amplification and potential signal degradation. To address this issue this paper presents a novel approach for reducing PAPR in OFDM systems using Fountain-coded Partial Transmit Sequence (PTS) schemes. Fountain codes well-known for their efficient erasure resilience and low-complexity decoding are incorporated into the PTS framework to enhance the PAPR reduction capabilities. The proposed implementation exploits the inherent parallelism in Fountain coding to generate a diverse set of candidate sequences efficiently which helps mitigate the PAPR-related performance degradation without introducing significant computational overhead. The report conducts a comprehensive performance evaluation of the Fountain-coded PTS schemes through extensive simulations in various OFDM scenarios including varying data rates channel conditions and constellation sizes.
