                 Abstract  With the urgent requirement of marine exploration and military application, underwater acoustic
                 communication should be high-speed and reliable. Orthogonal frequency division multiplexing (OFDM) has
                 been regarded as a new approach to underwater acoustic high-speed communication, and has been successfully
                 applied to this field as well as shows its superiority. Besides, the highly flexible adaptive platform is progressing
                 rapidly. It stimulates the development of reconfigurable and reprogrammable underwater acoustic modems
                 which to adapt to the demand of different experiments/application scenarios. In this paper, the progress of the
                 research on OFDM reconfigurable and reprogrammable underwater acoustic modems domestic and overseas is
                 introduced from the aspects of bandwidth, modulation scheme, data rate, transmission distance and bit error
                 rate. It also includes the overview of the technology. At the end of the paper, the future of OFDM reconfigurable
                 and reprogrammable underwater acoustic modems is prospected. We deem it needs the platform with block
                 receiving, adaptive, real-time and extensive, and believe the blossom of underwater network will promote the
                 development of intelligent underwater acoustic communication.
