Problems solved by technology

At present, commonly used decoding algorithms include SCL (Successive Cancellation list, continuous elimination list) algorithm and SC (Successive Cancellation, continuous elimination) algorithm, etc., but because the above decoding algorithm will consume more time for calculating the encoded non-information bits ( or instead freeze the path metric value corresponding to the bit), resulting in low efficiency of decoding the information bit

Abstract

The invention provides a data decoding method and device, and an electronic device. The method comprises the steps of obtaining a coded data set sent by a communication system; intercepting a target data set from the coded data set, wherein the target data set is a subset of the coded data set; calculating a decoding path metric value of each data in the target data set; and decoding the coded data set based on the decoding path metric value to obtain a decoding result of the coded data set. According to the invention, the time length required by decoding can be shortened, so that the data decoding efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data decoding method, device and electronic equipment. Background technique [0002] In the broadband satellite mobile communication system, there is a physical control channel used to carry control information. In practical applications, the physical control channel usually sends coded information bits. In order to obtain the information transmitted by the coded information bits, it is necessary to The information bits are decoded. At present, commonly used decoding algorithms include SCL (Successive Cancellation list, continuous elimination list) algorithm and SC (Successive Cancellation, continuous elimination) algorithm, etc., but because the above decoding algorithm will consume more time for calculating the encoded non-information bits ( Or instead freeze the path metric value corresponding to the bit), resulting in low efficiency of decoding the informatio...
