N2 - Presents a high speed adaptive multi-carrier underwater acoustic (UWA) communication system based on digital signal processing (DSP) real-time processing. Multi-channel frequency shift keying (MFSK) modulation, exact data synchronization and low-noise programmable gain amplifier(PGA) are used to decrease the error rate. With experiments on a condition of 1.5 m depth, and 2 km length, the system showed that the technique is effective in matching the real-time and voice recovery request, the transmission distance reached at least 2 km, and bit-error rate (BER) below 10-3.
