Abstract
Methods and systems described herein are directed to encoding information bits for transmission. The methods can include receiving a set of information bits (900) and determining a set of parity check bits (910). The set of information bits is concatenated with the set of parity check bits (920), and the information bits are polar encoded into a set of information bits and frozen bits (930). The encoded set of information bits is transmitted to a wireless receiver (940). In particular embodiments, each parity check bit in the set of parity check bits is the binary sum of the values of all bits in front of it. Other embodiments include generating a set of parity check bits based on a systematic block code on the least reliable bits of the set of information bits. The methods and systems described herein may be applied to 3GPP 5G mobile communication systems.
