Peak to Average Power Ratio Est. and Analysis in OTFS 6G Waveform by Using Selective Mapping Algorithm

Orthogonal time frequency space (OTFS) modulation has drawn recent interest due to its potential to mitigate the problems caused by extreme fading and delay spread in wireless communication systems. Despite its advantages, OTFS signals suffer from a high peak-to-average power ratio (PAPR) making it difficult to execute in practice with inefficient power amplification as well as results in higher distortion. In this study, OTFS modulation is examined in the context of Selected Mapping (SLM) technique to reduce the PAPR and improve its practical feasibility, and thereby intends to increase the spectrum and power efficiency. More specifically this study uses rigorous simulations and mathematical modelling by considering variables like computational load, hardware implementation feasibility, and system complexity to look at the effect of SLM on PAPR reduction. The results exploring the trade-offs between bit error rate, computational complexity, and PAPR reduction through systematic analysis provide a balanced viewpoint on the advantages and difficulties of integrating SLM, and they offer important insights into the real-world use of PAPR reduction strategies for OTFS. Using this research, enhanced performance and power efficiency can be achieved which paves the way for future developments in practical wireless communication implementations.
