Combined polar-LDPC design for channels with high noise

We combine polar and LDPC codes to address data correction for various low-power applications. We first use long low-rate LDPC codes that have parity checks of a low weight. Decoding performs several iterations of the belief propagation (BP) algorithm that recalculates the information bits only. Partially corrected bits are then passed to a short polar code that uses successive cancellation list (...
