In this paper, an FHMA acoustic communication system for multiple underwater robots based on hardware platform is developed. The sound card in the computer with sound box and microphone is used as the energy transduction to accomplish acoustic communication. For the hardware part, DS18B20 is taken for example as the data source to generate the original signals and MAX232 chip is adopted to connect...

This paper proposes an underwater acoustic communication system based on tamed spread spectrum and FHMA (Frequency Hopping Multiple Access) for multiple underwater robots. In this system, multiple underwater robots can communicate with the console on the water surface simultaneously successfully. The communication system is composed of tamed spread spectrum modulation and demodulation, frequency hopping...
This paper designs an underwater acoustic communication system based on QPSK-CDMA (Quaternary Phase Shift Keying-Code Division Multiple Access) for multiple underwater vehicles. Through this system, multiple underwater vehicles can communicate with the console on the water surface simultaneously without interference. The communication system is composed of channel encoding and decoding, spread spectrum...
This paper proposes an underwater acoustic communication system based on DS-CDMA (direct sequence code division multiple access) for multiple underwater vehicles. Multiple underwater vehicles in this system can communicate with the console on the water surface simultaneously without interference. The communication system is composed of channel encoding and decoding, spread spectrum modulation and...
In this paper, a kind of underwater acoustic communication system based on CDMA (code division multiple access) for multiple underwater robots is proposed. This system enables multiple underwater robots to communicate with the console on the surface of water simultaneously successfully. The whole communication process is composed of channel encoding and decoding, spread spectrum modulation and demodulation,...
