The invention relates to the technical field of communication, and discloses an underwater optical communication LDPC (Low Density Parity Check) coding processing method and device and a computer readable storage medium, and the method comprises the steps that a system constructs a first basis check matrix based on LDPC under the IEEE802.16 standard; updating the first base check matrix to obtain a second base check matrix; expanding the second base check matrix to obtain a check matrix; the transmitting end carries out coding based on the check matrix and outputs coding information; and the receiving end decodes the coded information and outputs original information. According to the coding processing method provided by the invention, the bit error rate of underwater optical communication can be quickly and effectively reduced, the adopted structured LDPC code is a code word stored in a check matrix, hardware implementation is facilitated, and the feasibility of the coding is verified through simulation.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to an underwater optical communication LDPC encoding processing method, device and computer-readable storage medium. Background technique [0002] The ocean is a land rich in resources, rich in energy and materials. From ancient times to the present, human beings have never stopped exploring the ocean. In the bottomless ocean, exploring the depths of the ocean is impossible without the support of communication technology. Underwater wired communication and underwater wireless communication are two branches of underwater communication technology research. The underwater wired communication technology has reached a relatively high level, and the underwater wired communication technology has been applied in national key projects such as the Jiaolong underwater deep diving project. Underwater wired communication has high transmission rate and strong anti-interference a...
