© 2021 Acoustical Society of America.Cooperative communication systems can solve the data rate limitations in underwater acoustic channels (UAC) introduced by their half-duplex (HD) nature and bandwidth limitations. In this paper, Hierarchical Modulation (HM) is introduced to both enhance the system throughput and spectral efficiency, as well as to enable various degrees of priority communication links. The proposed system utilizes HM with orthogonal frequency division multiplexing modulation (OFDM) in a two-way relay network (TWRN) using physical layer network coding (PLNC) to exchange information between two nodes operating in HD mode. The performance of the proposed PLNC-TWRN system is analysed via simulations using realistic UAC and numerical results are presented to demonstrate that it can significantly enhance the throughput.
