摘要： An encoding method for encoding input information bits using an encoder implemented with concatenation of a CRC-α coder and a polar coder is provided. The method includes performing Cyclic Redundancy Check (CRC) coding on as many information bits as a determined number of CRC coding bits among input information bits and performing polar coding on the CRC-coded information bits and other information bits than the CRC-coded information bits.

摘要： A method for encoding and decoding information data using a polar code is provided. The method for encoding includes segmenting information data into a plurality of first packets, generating a plurality of second packets corresponding to the plurality of first packets by adding a corresponding packet Cyclic Redundancy Check (CRC) code to each of the plurality of first packets, fragmenting each of the plurality of second packets into a plurality of data blocks, polar code encoding each of the plurality of data blocks included in a corresponding second packet of the plurality of second packets, and generating a plurality of third packets corresponding to the plurality of second packets by concatenating each polar code encoded data block included in the corresponding second packet. The method for decoding includes decoding the third packet to obtain the information data based on the method for encoding.

摘要： A method and an apparatus for encoding and decoding packets using a polar code is provided. The method includes acquiring a plurality of blocks constituting the packet, extracting a plurality of codeword candidates corresponding to the blocks, selecting some of the codeword candidates in a descending order of posterior probability among the codeword candidates corresponding to the blocks, combining the selected codeword candidates into a plurality of codeword combinations, selecting a codeword combination having the highest posterior probability and passed Cyclic Redundancy Check (CRC) test without error among the plurality of codeword combinations, and decoding the selected codeword combination. The packet encoding and decoding apparatus and method of the present disclosure is capable of encoding and decoding packets in a unit of blocks efficiently.
