CYCLIC REDUNDANCY CHECK (CRC) ATTACHMENTS FOR EARLY TERMINATION OF POLAR CODES

Title:

CYCLIC REDUNDANCY CHECK (CRC) ATTACHMENTS FOR EARLY TERMINATION OF POLAR CODES

Document Type and Number:

WIPO Patent Application WO/2018/184159

Kind Code:

A1

Abstract:

Certain aspects of the present disclosure relate to techniques and apparatus for improving performance of Polar codes. An exemplary method generally includes obtaining information bits, generating first cyclic redundancy check (CRC) bits based on the information bits, generating second CRC bits based on at least one of the information bits or the first CRC bits, generating polar codes based on the concatenation of the information bits with the first and second CRC bits, and transmitting a signal based on the polar codes.
