Abstract

The present invention provides a multi-threshold based Polar code SC-FLIP decoding method, device and storage device. The method reverses the decoding value of the decoding position where decoding is prone to error in the Polar code, and aims at the LLR value of the wrong position. The obvious difference between the LLR value and the correct position sets multiple thresholds for the error-prone position of SC decoding, and flips the decoding value of the corresponding decoding position whose LLR value is lower than the threshold to improve the bit error performance of SC decoding; at the same time, it provides A multi-threshold-based Polar code SC-FLIP decoding device and storage device are used to implement a multi-threshold-based Polar code SC-FLIP decoding method. The beneficial effects of the present invention are: by setting an independent threshold for each error-prone information bit, the decoding value of the error-prone position is reversed, effectively improving the decoding performance, and at the same time, under the same bit error performance, Reduce algorithm complexity; optimize the problem of high algorithm complexity when SC-FLIP has a low signal-to-noise ratio, and the algorithm complexity and bit error rate of the present invention are superior to traditional SC-FLIP decoding algorithms.

Description

Technical field [0001] The present invention relates to the field of communication technologies, and more particularly to a multi-threshold-based Polar code SC-FLIP decoding method, a device, and a storage device. Background technique [0002] On November 18, 2016, at the 3GPP RAN1 # 87 meeting in Nevada, Nevada, USA, a number of companies around the world in unified comparison, through the company's representative multi-wheel technology discussion, international mobile communication standardization organization 3GPP final Determine the Polar code as a control channel coding technology scheme for 5G EMBB (enhanced mobile broadband) scene. [0003] The Polar code is a new channel coding method constructed based on the channel polarization theory, and the Polar code has a deterministic construction method, and is the only one of the only channel encoding method capable of strictly demonstrating the channel capacity. . The Polar code is made by the N channels and the channel combini...
