Underwater Wireless Control and Transmission System Based on GSM Short Message

Because of the hostile seawater channel condition, underwater wireless communication becomes the bottleneck of the communication interlinking stations on sea, land and air all the while. In this paper, GSM short Message Service is applied to the underwater wireless control and data transmission. Using our underwater modem designed to overcome the effect of the hostile ocean channel, we can control the underwater device and receive data by sending short message. In order to mitigate the signal fading and inter-symbol interference (ISI) resulting from the multi-path effect (MPE), techniques of frequency hopping and frequency diversity are applied to the underwater acoustic communication. The experimental results show satisfactory performance.
