Abstract

A signal with the strongest energy may arrive at the receiver later than other signals do in the underwater acoustic channel on account of the sound velocity gradient distribution and the relative location between the receiving and sending nodes, etc. If the time-tracking is inexact, using a cyclic prefix only as guard interval may make the data of the current orthogonal frequency division multiplexing (OFDM) symbol for fast Fourier transform (FFT) be polluted by the data from the next symbol, thus destroying the orthogonality between subcarriers. The cyclic postfix is used in the OFDM underwater acoustic communication system to solve the above problems. Meanwhile, the cyclic postfix combines with the time reversal mirror technology for application in the OFDM underwater acoustic communication system to suppress the impact of sidelobe before the main peak of the time reversal channel and improve the channel equalization and the system performance. Theoretical analysis and simulation results show that the use of cyclic postfix in the OFDM underwater acoustic communication system is feasible and effective.
