Embodiment Construction
[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0032] In the embodiment of the present invention, two channels of underwater acoustic signals with the same content are obtained, and then the two channels of underwater acoustic signals are independently decoded. If the independent decoding is successful, the results obtained by decoding the underwater acoustic signals are output as received data; If the decoding of all the signals fails, the two underwater acoustic signals will be cross-decoded, and the result obtained by the cross-decoding will be output as the received data, which solves the existing underwater acoustic communication technology...
