Query: Fast Software Polar Decoders   Among error-correcting codes, polar codes are the first to provably achieve
channel capacity with an explicit construction. In this work, we present
software implementations of a polar decoder that leverage the capabilities of
modern general-purpose processors to achieve an information throughput in
excess of 200 Mbps, a throughput well suited for software-defined-radio
applications. We also show that, for a similar error-correction performance,
the throughput of polar decoders both surpasses that of LDPC decoders targeting
general-purpose processors and is competitive with that of state-of-the-art
software LDPC decoders running on graphic processing units.
