Abstract
Polar codes provably achieve the symmetric capacity of a memoryless channel while having an explicit construction. The adoption of polar codes however, has been hampered by the low throughput of their decoding algorithm. This work aims to increase the throughput of polar decoding hardware by an order of magnitude relative to successive-cancellation decoders and is more than 8 times faster than the current fastest polar decoder. We present an algorithm, architecture, and FPGA implementation of a flexible, gigabit-per-second polar decoder.Other Versions
