Polar code encoding method and device

Abstract

The invention relates to the technical field of communication, and discloses a polar code encoding method and device for providing a new encoding checking method. The method comprises steps: at leasttwo to-be-checked first bit sequences are subjected to encoding checking respectively to acquire at least two checked bit sequences, wherein the union of the at least two to-be-checked first bit sequences is K information bits and K is a positive integer; the K information bits and the at least two checked bit sequences are interleaved, or, the first-part information bit sequence and the first checked bit sequence are interleaved to acquire a third interleaved bit sequence, wherein the second-part information bit sequence except the first-part information bit sequence in all information bit sequences, a second checked bit sequence and a third checked bit sequence form a second bit sequence; and polarized Polar encoding is carried out on the second bit sequence.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a method and device for encoding a Polar code. Background technique [0002] Cyclic redundancy check (CRC) coding is the most commonly used error checking code in the field of data communication. The characteristic of CRC coding is that the lengths of the information field and the check field can be selected arbitrarily. In a communication system, CRC coding is used to detect whether data transmission is correct, and to control the probability of false alarm (English: false alarm). [0003] One implementation of CRC encoding is in the form of a shift register. figure 1 It is a commonly used method of implementing CRC encoding in the form of a shift register (referred to as a register). The feedback tap of the register is determined by the CRC polynomial [1 0 1 0 1], and the register content is initialized to a preset value. During encod...
