Polar codes have recently emerged as one of the most favorable capacityachieving error correction codes due to their low encoding and decoding complexity. However, because of the large code length required by practical applications, the few existing successive cancellation (SC) decoder implementations still suffer from not only high hardware cost but also long decoding latency. In this paper, a data-flow graph (DFG) for the SC decoder is derived. A complete hardware architecture is first… CONTINUE READING
