A NTP-BALS Receiving Algorithm for MIMO-OTFS Dual-Hop Communication Systems

This paper focuses on a large-scale MIMO dual-hop communication system with OTFS modulation, where the received signal conforms to the PARAFAC model embedded in the TUCKER. A NTP-BALS receiving algorithm based on the tensor structure of received signals is proposed, which effectively obtains channel state information through iterative solving. The simulation results show that the algorithm outperforms the traditional TST method regarding normalized mean square error and bit error rate, demonstrating its superior performance.
