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...

Abstract

The invention is applicable to the field of underwater acoustic communication technology, and provides a method and apparatus for decoding underwater acoustic signals, and a method and apparatus for sending the underwater acoustic signals. The method comprises the following steps: receiving a first underwater acoustic signal and a second underwater acoustic signal; separately decoding the first underwater acoustic signal and the second underwater acoustic signal through a preset first decoding rule to obtain a first decoding result; and if the first decoding result indicates that the decoding of both of the first underwater acoustic signal and the second underwater acoustic signal is failed, performing cross decoding on the first underwater acoustic signal and the second underwater acoustic signal through a preset second decoding rule to obtain a second decoding result. According to the method provided by the invention, two paths of underwater acoustic signals having completely the same contents are obtained at the same time, independent decoding and cross decoding are separately performed on the two paths of underwater acoustic signals to attempt to obtain correct underwater acoustic signals for decoding, and the problem that the existing underwater acoustic communication technology mainly improves the communication reliability through a large number of check bits and a complex check algorithm, resulting in low communication efficiency and large decoding operation amount, is solved.

Description

technical field [0001] The invention belongs to the technical field of underwater acoustic communication, and in particular relates to an underwater acoustic signal decoding method, a sending method and a device thereof. Background technique [0002] As one of the commonly used communication methods, underwater acoustic communication has been applied to major communication networks. However, since underwater acoustic communication is easily affected by environmental factors, a check code is often added to the signal during the communication process to improve the reliability of communication and reduce the bit error rate. [0003] The existing underwater acoustic communication technology mainly uses a large number of check digits and complex check algorithms to improve the reliability of communication. However, a large number of parity bits will reduce the communication efficiency of underwater acoustic communication, and the complex parity algorithm will also bring a large...
