Method, apparatus, device, and computer-readable storage medium for enhancing far performance

Abstract

The invention discloses a method for enhancing FAR performance, comprising: acquiring the maximum PM value and the minimum PM value among the PM values ​​of multiple decoding paths, and acquiring the PM value of the decoding path passing CRC among the multiple decoding paths , wherein, a decoding path corresponds to a PM value; according to the PM value, the maximum PM value and the minimum PM value of the decoding path through the CRC, the judgment parameter is determined; according to the judgment parameter and the preset parameter, the decoding path through the CRC is determined Whether the codeword transmitted on the upper part is a valid codeword. The invention also discloses a device, equipment and computer-readable storage medium for enhancing FAR performance.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method, device, device and computer-readable storage medium for enhancing False Alarm Ratio (FAR) performance. Background technique [0002] Polar code is a channel coding scheme based on channel polarization digital signal processing technology. Channel polarization introduces correlation into binary memoryless channels through channel segmentation and channel combination operations, so as to obtain a new set of interdependent Binary polarized channel; when the number of channels participating in channel polarization is large enough, the channel capacity of the obtained polarized channel (bit channel) will appear polarized, that is, the capacity of some channels will tend to 1, and the capacity of the rest will tend to is at 0; using this polarization phenomenon, free bits can be carried on bit channels with high channel capacity, and fixed bits can be car...

[0002] Polar code is a channel coding scheme based on channel polarization digital signal processing technology. Channel polarization introduces correlation into binary memoryless channels through channel segmentation and channel combination operations, so as to obtain a new set of interdependent Binary polarized channel; when the number of channels participating in channel polarization is large enough, the channel capacity of the obtained polarized channel (bit channel) will appear polarized, that is, the capacity of some channels will tend to 1, and the capacity of the rest will tend to is at 0; using this polarization phenomenon, free bits can be carried on bit channels with high channel capacity, and fixed bits can be carried on bit channels with low channel capacity, thereby improving transmission reliability; When the information bits of the polar code transmitted on the bit channel are subjected to cyclic redundancy check (Cyclic Redundancy Check, CRC), there will be error detection and error detection, which will lead to insufficient FAR performance
