Abstract
According to certain embodiments, a method is provided for generating soft information for code bits of polar codes. The method includes receiving, by a decoder of a receiver, soft information associated with coded bits from a first module of the receiver and using a tree structure of the polar code to generate updated soft information. The updated soft information is output by the decoder for use by a second module of the receiver.
Claims28
A method in a receiver for generating soft information for code bits of polar codes, the method comprising:
- receiving, by a decoder of the receiver, soft information associated with coded bits;
- using, by the decoder, a tree structure of the polar code to generate updated soft information;
- and
- outputting, by the decoder of the receiver, the updated soft information.
A decoder in a receiver for the soft output generation for code bits of polar codes, the decoder comprising:
- memory storing instructions;
- and
- processing circuitry operable to execute the instructions to cause the decoder to:
- receive soft information associated with coded bits;
- use a tree structure of the polar code to generate updated soft information;
- and
- output the updated soft information.
