Abstract
A system and method for polar code coding with information bits placed in particular bit indexes are disclosed herein. In one embodiment, a method for channel coding includes: associating, by a polar code encoder, a first bit sequence with first bit indexes of a polar code input; associating, by the polar code encoder, a second bit sequence with second bit indexes, wherein the first bit indexes have a higher reliability than the second bit indexes; and encoding, by the polar code encoder, both the first bit sequence and the second bit sequence using a generator matrix to generate encoded bits.

A method for channel coding, comprising:
- obtaining information bits to be encoded, wherein the information bits comprise a first bit sequence and a second bit sequence, wherein the first bit sequence requires a lower bit error ratio than the second bit sequence;
- associating, by a polar code encoder, the first bit sequence of the information bits with first bit indexes of a polar code input;
- associating, by the polar code encoder, the second bit sequence of the information bits with second bit indexes of the polar code input, wherein the first bit indexes have a higher reliability than the second bit indexes;
- and
- encoding, by the polar code encoder, both the first bit sequence and the second bit sequence using a generator matrix to generate encoded bits.
A method for channel coding, comprising:
- receiving, by a polar code decoder, encoded information bits comprising a first bit sequence and a second bit sequence, wherein:
- the first bit sequence requires a lower bit error ratio than the second bit sequence,
- the first bit sequence is associated with first bit indexes of a polar code,
- the second bit sequence is associated with second bit indexes of the polar code,
- the first bit indexes have a higher reliability than the second bit indexes, and
- the first bit sequence and the second bit sequence are encoded based on the polar code using a generator matrix;
- and
- decoding, by the polar code decoder, the encoded information bits based on the polar code.
