| Summary: | 碩士 === 國立臺灣海洋大學 === 電機工程學系 === 98 === In the thesis, we propose a system to transmit underwater image which is consist of orthogonal frequency division multiplexing, space-time block coding, power control, chaos encryption and adaptive modulation techniques. The system not only achieves the requirement of underwater image transmission, but also can provide the accuracy and confidentiality. The combination of STBC and OFDM can achieve maximum transmission power at a minimum transmission power. In addition, the chaos encryption mechanism can provide a good protection for the underwater image. The simulation results are consistent with our argument.
