FIELD: radio engineering, communication.
SUBSTANCE: provided: obtaining a congruent sequence according to the length of the target polar code; performing sorting processing of the congruent sequence according to previously established rule to get the reference sequence; defining the function of conversion according to the congruent sequence and reference sequences; and alternation of the target polar code according to conversion functions to generate alternated output bits. The bits, alternated in that way, have a uniform structure that reduces the frequency of frame errors and increases HARQ-productivity, thereby increasing the reliability of communication.
EFFECT: increase in the HARQ-productivity.
