1. A method comprising:
obtaining an input bit sequence containing N
_{1}+N_{2 }bits, the input bit sequence including information bits and frozen bits, where N_{1 }and N_{2 }are different powers of a polar code kernel size;polar encoding N
_{1 }bits of the input bit sequence with a first constituent polar encoder to produce a first set of N_{1 }polar encoded bits;polar encoding N
_{2 }bits of the input bit sequence with a second constituent polar encoder to produce a second set of N_{2 }polar encoded bits;after the encoding the N
_{1 }bits and the encoding the N_{2 }bits, combining at least some of the first set of N_{1 }polar encoded bits with at least some of the second set of N_{2 }polar encoded bits with a first additional polarizing stage to produce a set of N_{1 }combined bits; andgenerating an asymmetric polar encoded codeword of length N
_{1}+N_{2 }consisting of the set of N_{1 }combined bits and the second set of N_{2 }polar encoded bits. |
