Abstract:
Polar encoding using two or more concatenated cyclic redundancy check (CRC) data values may enhance CRC-aided successive cancellation list decoding in a communication system. A polar encoding method may include determining first CRC data from source data, combining the source data and the first CRC data to form first combined data, determining second CRC data from the first combined data, and combining the source data, the first CRC data, and the second CRC data to form second combined data.

Claim (Index 21):
An apparatus for communication, comprising:\n a processing system comprising a processor and memory, the processing system configured to: control reception of input data over a channel, the input data representing a polar-encoded combination of source data, second cyclic redundancy check (CRC) data, and first CRC data, the second CRC data encoding a combination of the source data and concatenated first CRC data, the first CRC data encoding the source data; and decode the input data using a plurality of successive decoding stages by the processing system being configured to, at each stage: generate exactly two duplicate decoding paths for each of L paths to provide a set of 2 L candidate paths, the two duplicate decoding paths representing respective decisions of 0 and 1, where L is an integer greater than 1; evaluate, based on the source data, the set of 2 L candidate paths to determine a set of L most reliable paths out of the set of 2 L candidate paths; and remove from further evaluation all but the set of L most reliable paths, and preserving the set of L most reliable paths for a next decoding stage, wherein decoded data remains following the plurality of successive decoding stages; and baseband circuitry for further processing the decoded data.
