building polar code based on mutual information

摘要

Wireless communication methods, systems and devices are described for building polar code based on mutual information. a wireless device can receive a code word over a wireless channel, where the encoded code word uses a polar code. the wireless device can identify a set of polar code bit locations corresponding to the information bits of an encoded information bit vector. the set of bit locations can be determined based, at least in part, on an order of reliability of the bit locations of the polar code, and the order of reliability can be determined based, at least in part, on a recursive model which includes at least one mutual information transfer function that is applied at each polarization multi-stage polarization stage of the polar code. the wireless device can decode the received code word to obtain the bit vector of information in the set of bit locations.
