Abstract
Orthogonal Time Frequency Space (OTFS) is the advanced stage of modulation for this fast-growing generation. This is the waveform proposed to be used in next-generation communication systems i.e., 6G, as it has the advantage of high data rate, better flexibility, requires a less cyclic prefix and less amount of peak to average power ratio (PAPR) compared to Orthogonal Frequency Division Multiplexing (OFDM). To reduce the amount of PAPR in the OTFS, the best method is the classical selected mapping (SLM) technique. This paper presents the PAPR analysis in OTFS modulation by using classical SLM and the obtained results are compared against the OFDM modulation.
