초록

This paper investigates a complex wavelet-Aided multiple-input and multiple-output orthogonal time-frequency space (CW-MIMO-OTFS) scheme operating in low earth orbit (LEO) satellite systems. We present a mathematical model for the proposed CW-MIMO-OTFS system constructed using a straightforward matrix multiplication approach. The investigation utilized the complex form of the Haar and Daubechies wavelet functions. Additionally, the performance evaluation of the proposed scheme focused on analyzing the bit error rate (BER) and Cramér-Rao bound (CRB) characteristics for joint sensing and communications. The simulation findings demonstrate the superiority of the proposed CW-MIMO-OTFS approach over existing state-of-The-Art solutions in terms of the BER and CRB performance compared to the W-MIMO-OTFS scheme in LEO satellite systems.
