Abstract

In view of characteristics of channel parameters changing with time and space of underwater acoustic channel, a rateless transmission scheme for adaptive transmission over underwater acoustic channels is studied in this paper. The scheme utilizes the characteristics of LT coding without fixed coding rate, and the communication efficiency is further improved through single-carrier frequency-domain equalization. Simulation results show that the scheme we proposed can effectively reduce the computational complexity compared to the rateless coding system under classical time-domain equalization. With achieving the same reliable information transmission in the same underwater acoustic channel, the redundancy required by the proposed scheme is about 1/3 of the classical retransmission method, which improves the efficiency of information transmission.
