PAPR Reduction,and BER Performance in MIMO OFDM Using Conventional Techniques with Modified PTS and SLM

Abstract Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) is a widely adopted transmission technique in modern wireless communication systems due to its high data rate and robustness against multipath fading. However, high Peak-to-Average Power Ratio (PAPR) remains a major drawback, leading to nonlinear distortion, degraded Bit Error Rate (BER), This paper presents a comparative study between conventional PAPR lessening techniques and a low-complexity PAPR reduction approach using a Modified Partial Transmit Sequence (PTS) scheme with a Hybrid Artificial Bee Colony–Firefly (ABC–FF) algorithm. The comparison is carried out in terms of PAPR reduction capability, BER performance, and computational complexity. Simulation results demonstrate that the proposed Modified PTS with Hybrid ABC–FF algorithm achieves superior PAPR reduction, improved BER performance, compared to conventional methods, making it suitable for next-generation wireless communication systems.To progress the existing PAPR reduction techniques, we have incorporated ideal SLM and PTS based PAPR reduction strategy in parallel. By utilizing, the OGWO algorithmMoreover, the OGWO optimization based PAPR reduction technique will provide better performance and it was been promoted as an uncomplicated way for PAPR reduction. The proposed approach will be analyzed with various novel PAPR reduction schemes to show the effectiveness
