Abstract

The invention discloses a polar code segment coding method. The method comprises the following steps: determining a coded code length N according to a to-be-coded information bit number and a code rate; according to the N, the minimum segment code length and the maximum segment code length, determining the reserved segment number of each segment in the segments with the b-a+1 segment code lengthsand the reserved code length corresponding to the N, wherein the minimum segment code length is 2[Lambda]a, and the maximum segment code length is 2[Lambda]b; determining the segment number of each segment according to N, the reserved code length, the segment code length of each segment and the reserved segment number of each segment, wherein N corresponds to an S segment, and the segment code length of the ith segment in the S segment is larger than or equal to the segment code length of the (i+1)th segment in the S segment; determining a target information bit number of the S-segment segmentaccording to the code rate and the segment code length of the S-segment segment; and performing polarization code encoding on the information bits to be encoded according to the target information bit number of the S segments. By implementing the invention, the performance of the low-power-consumption communication system can be effectively improved under the condition of meeting the decoding andreporting delay limitation.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to a polar code segmentation encoding method and communication equipment. Background technique [0002] For a communication system that is extremely sensitive to time delay, after receiving the data, the receiving device needs to process the data within a very short time and reply with an acknowledgment character ACK (Acknowledgment). For example, in the Bluetooth system, the interval between the mobile phone sending data and receiving the ACK of the main earphone is 189us. After the main and auxiliary earphones receive all the information sent by the mobile phone, there is a 15us time margin for decoding and data reporting. Systems such as Bluetooth that require low power consumption generally limit the power of information reporting, further limiting the reporting rate of information bits. Currently, the Bluetooth system usually adopts a coding method without ch...
