Zhu, T. and Zhang, F., 2020. Design of marine two-way voice communication system based on human-computer interaction. In: Malvárez, G. and Navas, F. (eds.), Global Coastal Issues of 2020. Journal of Coastal Research, Special Issue No. 95, pp. 1389-1394. Coconut Creek (Florida), ISSN 0749-0208.

In order to improve the long-distance transmission and speech receiving and receiving ability of marine bidirectional voice communication, the marine bi-directional voice communication transmission technology based on human-computer interaction is proposed in this paper. The channel equalization model of marine bi-directional speech communication is designed to modulate the marine bi-directional speech communication signal in the space-disguised coherent multi-path channel of marine bi-directional speech information transmission, and the linear equalization controller is used to filter the interference. The fractionally spaced equalizer is designed to deal with the anti-interference of the marine bidirectional speech communication signal, to improve the real-time performance of the marine bi-directional speech transmission, and to design the receiver at the output terminal to realize the accurate feedback of the marine bi-directional speech communication signal. The hardware modularization design of marine bi-directional speech communication system based on man-machine interaction model is carried out. The main function modules of the system include data receiving module, speech information processing module, human-computer interaction module and receiver conversion module. The simulation results show that the proposed method has low bit error rate (BER) for long-distance transmission of marine bi-directional speech communication signals, and can realize real-time monitoring and voice communication of marine bi-directional speech communication.
