|1. (WO2018184493) DATA ENCODING AND DECODING METHOD AND DEVICE|
|Applicants:||HUAWEI TECHNOLOGIES CO., LTD.
|Title:||DATA ENCODING AND DECODING METHOD AND DEVICE|
Disclosed in an embodiment of the present invention is a data encoding method characterized by comprising: performing polar code encoding on multiple data blocks to be encoded to obtained encoded data blocks, wherein each of the multiple data blocks carries feature information, and after the feature information has undergone polar code encoding, a relationship between the feature information carried by two adjacent preceding and subsequent data blocks is satisfied; using a corresponding scrambling sequence to perform descrambling on the feature information carried by the subsequent data block to obtain the feature information carried by the preceding data block; and outputting the multiple encoded data blocks in an order from preceding data blocks to subsequent adjacent data blocks.
