Title:
POLARIZATION CODE CONSTRUCTION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/078273
Kind Code:
A9
Abstract:
The embodiments of the present application relate to the technical field of communications. Provided are a polarization code construction method and device. The method comprises: obtaining a polarization weight spectrum of each polarization channel; calculating the upper bound of the error probability of each polarization channel according to the obtained polarization weight spectrum, the distribution probability density of fading factors of a fading channel, and the signal-to-noise ratio of the fading channel; for each polarization channel, taking the logarithm of the upper bound of the error probability obtained by calculation for the polarization channel, and obtaining the reliability metric of the polarization channel according to the logarithm-taking result, wherein the smaller the metric, the higher the reliability of the polarization channel; and sorting all polarization channels in descending order of reliability, and selecting some polarization channels having the highest reliability for transmitting information bits, and the remaining polarization channels for transmitting frozen bits. According to the embodiments of the present application, performing polarization code construction under fading channel conditions can improve the efficiency of polarization code construction.
