Abstract
The embodiments of the present application provide a polar code construction method and apparatus, which relate to the field of communications technology. The method comprises: obtaining a polar weight spectrum for each polarized channel; calculating an upper bound of error probability of each polarized channel based on the obtained polar weight spectrum, distribution probability density of a fading factor of a fading channel, and a signal-to-noise ratio of the fading channel; taking a logarithm of the calculated upper bound of the error probability for each polarized channel and obtaining a reliability metric of the polarized channel based on the taken logarithm, wherein the smaller the metric value is, the higher the reliability of the polarized channel is; sorting all polarized channels in an ascending order of the reliability metric and selecting part of the polarized channels having a lowest reliability metric for transmitting information bits and the remaining polarized channels for transmitting frozen bits. According to the embodiments of the present application, performing polar code construction under the condition of a fading channel can improve the efficiency of polar co…
