Abstract

This paper proposes a filter bank multicarrier (FBMC)-based underwater transmission scheme for voice and image signals. In this scheme, FBMC transmission technology, low-density parity-check (LDPC) channel coding, adaptive binary phase shift keying (BPSK) modulation or offset quadrature amplitude modulation (OQAM), and a power assignment mechanism are integrated into an underwater voice and image transmission system. The bit error rates (BERs) of voice and image signals for underwater transmission are required to be less than 10-3, and 10-4, respectively. The BER performances of the proposed scheme in an underwater acoustic channel were demonstrated through simulations, and the power saving ratios for the underwater transmissions of voice and image signals were explored. The simulation results show that the proposed underwater transmission system can achieve a lower transmission-power consumption or a higher transmission data rates compared to a system without the power assignment mechanism. The results also indicate that the proposed system can be used for advanced underwater signal transmissions.
