The embodiment of the invention provides a polarization code construction method and device, and relates to the technical field of communication, and the method comprises the steps: obtaining the 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 the fading factor of the fading channel and the signal-to-noise ratio of the fading channel; for each polarization channel, carrying out logarithm taking processing onthe upper bound of the error probability obtained through calculation for the polarization channel, obtaining the reliability measurement of the polarization channel according to the logarithm takingprocessing result, wherein the smaller the measurement value is, the higher the reliability of the polarization channel is; and sorting all polarization channels according to a sequence from high reliability to low reliability, selecting a part of polarization channel with the highest reliability for transmitting information bits, and using the rest polarization channels for transmitting frozen bits. According to the embodiment of the invention, the polar code construction is carried out under the fading channel condition, and the polar code construction efficiency can be improved.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for constructing polar codes under fading channel conditions. Background technique [0002] In the field of communication technology, since there is noise interference in the channel for transmitting information, it is necessary to perform polarization processing on the channel to obtain each polarized channel, and some of the obtained polarized channels tend to be noise-free channels, and the remaining polarized channels tend to be noise-free channels. The channel tends to be a full noise channel, and then the information transmission is realized through the polarized channel. When transmitting information through a polarized channel, determine the polarized channel for transmitting information bits and the polarized channel for transmitting frozen bits. The above-mentioned information bits are randomly sent by the information sending end with equal pr...
