This paper proposes a 2 × 2 direct mapping (DM) based of an underwater acoustic transmission (UAT) scheme for data signals based on filter bank multicarrier (FBMC)-low density parity check (LDPC). The 2 × 2 DM multiple-input multiple-output (MIMO) transmission mechanism, FBMC modulation, LDPC channel coding, adaptive binary phase shift keying (BPSK) modulation and four offset quadrature amplitude modulation (4-OQAM), and power assignment mechanism are integrated. The performances of bit error rates (BERs) and data error rates (DERs) of the proposed underwater data transmission scheme with perfect channel estimation (PCE) (0%), and the channel estimation errors(CEEs) of 5%, 10%, and 20% are investigated. The bit error rates (BERs) of data signals for underwater transmission must be less than 10–5. The transmission power weightings and ratios of power saving (PS) for the proposed underwater acoustic transmission system are explored through simulations. From these simulation results, we evaluate the performances of the proposed advanced data UAT scheme.
