ENHANCED INFORMATION SEQUENCES FOR POLAR CODES

Abstract:

Systems and methods are disclosed for performing polar encoding of a number of information bits for transmission in a wireless communication system in a manner that is optimized for a specific code length. In some embodiments, a method of operation of a transmit node in a wireless communication system comprises performing polar encoding of a set of K information bits to thereby generate a set of polar-encoded information bits where the K information bits are mapped to the first K information bit locations specified in an information sequence S.sub.N which is a ranked sequence of N information bit locations among a plurality of input bits for the polar encoding where N is equivalent to a code length, a size of the information sequence S.sub.N is greater than or equal to K, and the information sequence SN is optimized for a specific value of the code length N.
