Abstract

In this paper, a multi-input multi-output underwater acoustic communication method based on OTSM-IM (MIMO-OTSM-IM) is proposed. The method introduces the index modulation technique and the multi-input multi-output technique into the OTSM system in order to achieve a balance between spectral and energy efficiency, as well as to significantly improve data transmission reliability. In particular, the method employs constellation and position to transmit information bits simultaneously in the delay-sequence domain with both single-input-single-output and multi-input-multi-output transmission modes, while the receiver side is detected using maximum likelihood detection method. The final simulation results show that MIMO-OTSM-IM exhibits significant advantages in enhancing the performance of the error rate for the system.
