A Complex Wavelet-Based OTFS Scheme for LEO Satellite Communication

A Complex Wavelet-Based OTFS Scheme for LEO Satellite Communication

This study investigates a wavelet-aided orthogonal time-frequency space (W-OTFS) modulation system operating in low earth orbit (LEO) satellite systems. The discrete wavelet transform (DWT) underlying the complex input signals (high-order modulation) is not applicable in the W-OTFS system because of...
