碩士 / 國立臺灣海洋大學 / 電機工程學系 / 106 / In the thesis, a 2 x 2 direct mapping (DM) based filter bank multicarrier (FBMC)- low density parity check (LDPC) code underwater acoustic transmission scheme for data signals is proposed. The 2 x 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 (0%), and with the channel estimation errors of 5%, 10%, and 20% are investigated. The bit error rates (BERs) of data signals for underwater transmission are required to be less than . The transmission power weightings and the 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 underwater acoustic transmission scheme.
