In underwater acoustic communication, carrier tracking is adversely affected by Doppler and time-variation of the channel, which caused bad performance of the receiver. Differentially coherent detection based on the premise that there is no intersymbol interference (ISI) and the bad performance is produced when carrier frequency shift is enormous. In order to solve this problem, we propose an adaptive...
Real-time data transmission with high data rate and low bit error rate is realized by underwater multi-carrier acoustic communication system, which plays an important role in AUV. OFDM (orthogonal frequency division multiplexing) is an attractive multi-carrier communication method around the world. According to the requirements of OFDM signal transmission in underwater multi-carrier acoustic communication,...
