MUTUAL-INFORMATION BASED RECURSIVE POLAR CODE CONSTRUCTION

Title:

MUTUAL-INFORMATION BASED RECURSIVE POLAR CODE CONSTRUCTION

Document Type and Number:

WIPO Patent Application WO/2018/153343

Kind Code:

A1

Abstract:

Methods, systems, and devices for wireless communication are described. To encode a vector of bits using a polar code, an encoder may allocate information bits of the vector to polarized bit-channels associated with a channel (e.g., a set of unpolarized bit-channels) used for a transmission. In some cases, the polarized bit-channels may be partitioned into groups associated with different values of some associated reliability metric (s). The information bits may be allocated to the polarized bit-channels based on the reliability metrics of the different polarized bit-channels and the overall capacity of a transmission. That is, the bit locations of a transmission may depend on the reliability metrics of different polarized bit-channels and the overall capacity of the transmission. To facilitate puncturing, the overall capacity of the transmission may be adjusted and the unpolarized bit-channels may be partitioned into polarized bit-channels based on the adjusted capacity.
