Abstract

In order to improve the image transmission quality of underwater visible light communication, this paper designs an optimal scheme of the underwater image transmission system based on blue visible light communication. In the hardware circuit module, the trans-impedance amplifier circuit of the T-feedback network is used to improve the signal receiving performance. Due to the bad feature of the underwater channel, a fast likelihood blind detecting algorithm was adopted to detect, collect and process the data in this article. The method proposed in the paper is able to reduce BER (Bit Error Rate) as well as speed up computation. It can be seen from the experimental results that the scheme of the system optimization effectively decreases DC bias of the photoelectric receiver, as well as decreases the computation complexity and improves the transmitting efficiency under the condition of meeting the requirements for the specific BER of the receiving signal.
