Abstract: Encoding devices and methods, arranged to execute encoding, wherein an input vector for polar encoding is computed, wherein the input vector comprises a set of information bits and a set of frozen bits, and an intermediate codeword is generated by executing a polar encoding of the input vector. Further, punctured and shortened bits are removed from the intermediate codeword, to obtain a reduced intermediate codeword, and an output codeword is generated by applying a permutation operation on the reduced intermediate codeword. A sequence of extension bits is selected from the intermediate codeword bits and information bits, and modulated symbols are generated by applying bitmapping on the output codeword and on the sequence of extension bits.

Abstract: The device and method disclosed herein are configured for generating a polar code of length N and dimension K on the basis of an original polar code being defined by a code sequence S having Nmax bit indices sorted from least reliable to most reliable sub-channels. The device comprises a processing unit configured to: (a) generate an auxiliary code sequence having Nmax/2 bit indices by removing bit indices greater than or equal to Nmax/2 from the code sequence S; (b) remove from the auxiliary code sequence the last NR bit indices to generate a modified auxiliary code sequence; and (c) generate the polar code of length N and dimension K by puncturing the original polar code on the basis of a puncturing set defined by the last p=Nmax−N bit indices of the modified auxiliary code sequence.

Abstract: A method comprises: obtaining a coded bit sequence by performing PC-polar coding on information bits based on first constructor parameters; and sending the coded bit sequence. A check equation of the first constructor parameters includes a first element representing a check-required information bit position and a second element representing a check bit position, the first element corresponds to a first vector (V1) in a generator matrix for PC-polar codes, the second element corresponds to a second vector (V2) in the generator matrix, and if a first Hamming weight (HW1) of V1 is the same as a second Hamming weight (HW2) of V2, then a third Hamming weight (HW3) of an addition modulo 2 vector is greater than HW1 and greater than HW2, or if HW1 is different from HW2, then HW3 is greater than a smaller one of the HW1 and HW2.
