Multiple Access Using Orthogonal Time-Frequency Space Modulation

摘要

An orthogonal time-frequency space (OTFS) modulation scheme that achieves multiple accesses by multiplexing a plurality of signals at the transmitter side allows for the allocation of transmission resources for the first signal and the second signal, the combination and switching to a transmission format via OTFS modulation , And transmission of the signal through the communication channel. At the receiver, the upper multiplexed signals are reconstructed using the orthogonality property of the basis functions used for multiplexing at the transmitter.
