Title: POLAR CODE ENCODING AND DECODING METHOD, SENDING DEVICE AND RECEIVING DEVICE
Abstract:
The present application provides a polar code decoding and encoding method, a sending device and a receiving device, helping to address the deficiencies in the prior art in code rate, reliability and complexity during short/medium packet transmission. Said method comprises: a sending device pre-storing at least one mother code sequence, each mother code sequence being formed by at least one sub-sequence and at least one sub-set, an element in each sub-sequence or sub-set being the sequence number of a polar channel, each sub-sequence or sub-set comprising at least one sequence number, the relative positions of sequence numbers in each sub-sequence being arranged in the order of magnitude of the reliability of polar channels; the sending device determining, according to the code length of a target polar code, an information bit sequence number set from the at least one mother code sequence; the sending device performing polar encoding of information bits according to the information bit sequence number set.
