Abstract
The present disclosure is directed to a system and method for decoding a polar encoded codeword using a frozen bit pattern determined based on a frozen bit pattern derived for a trellis decoder with a different routing structure between each of a plurality of processing stages. The frozen bit pattern can be determined based on the frozen bit pattern derived for the trellis decoder with the different routing structure between each of the plurality of processing stages such that a belief propagation decoder that uses a plurality of time-multiplexed processing elements with a fixed routing interconnect can still achieve a high decoding performance.
