Underwater acoustic communication system with trellis coded modulation (TCM) technique and DSP implementation
Abstract:
This paper discusses in detail the principle for Trellis Coded Modulation (TCM) and its application in underwater acoustic communication. The authors have implemented an underwater wireless communication system with the ability of character transmission by adopting high performance DSP chip TMS320C542 produced by TI Company. The testing result indicates that the Trellis Coded Modulation technique can improve evidently the peformance with underwater wireless communication system.
Key words:  trellis coded modulation  acoustic underwater communication  simulation  DSP implementation
