Title: CONSTRUCTING, REPRESENTING, AND ENCODING POLAR CODES
Abstract:
Disclosed herein are user equipment (UE) and base station (eNB) apparatus and methodology for polar code construction, representation and encoding/decoding. An apparatus of a UE may include memory and processing circuitry coupled to the memory. The processing circuitry is configured to generate input vectors by adding zeros to a set of input bits. A polar code permutation vector is generated based on estimates of channel reliability of a transmission channel. The estimates are determined using a pre-defined range of signal-to-noise ratios (SNRs) of the transmission channel. The polar code permutation vector is applied to the input vectors to obtain a output permuted vectors. The output permuted vectors are polar coded using a generator matrix, to generate an encoded information block for transmission to an evolved Node-B (eNB) via the transmission channel.
