摘要: Abstract:In this paper, we propose an orthogonal frequency division multiplexing (OFDM) based underwater
acoustic multimedia system. An essential feature of this system is that it offers larger power and schemes
providing significant error protection for the transmission sensor data information that requires higher quality of
service (QoS). To realize maximum resource utilization, or minimum total transmission power, we also include
an adaptive modulation strategy into the system. Thus, in the proposed underwater acoustic multimedia system,
high power, low speed modulation, and scheme providing significant error protection schemes are employed for
the transmission of sensor data messages that require a stringent bit-error rate (BER). In contrast, low power,
high speed modulation, and less capable error protection schemes are provided for messages that can tolerate a
high BER. A simulation is carried out to verify the proper functioning of the proposed system in a practical
underwater acoustic multimedia scenario.
