Symbol interferometry and companding transform for PAPR reduction of OTFS signal
This paper presents methods for reducing the peak-to-average power ratio (PAPR) of the orthogonal time frequency space (OTFS) signal. These methods mainly consist of two operations: symbol interferometry (SI) and either μ-law or A-law companding. SI spreads the data of one OTFS symbol onto all symbo...
