Fast Successive-Cancellation Decoding of Polar Codes: Identification and Decoding of New Nodes
Muhammad Hanif, Masoud Ardakani · IEEE Communications Letters · 2017
The decoding latency of polar codes can be reduced by implementing fast parallel decoders in the last stages of decoding. In this letter, we present five such decoders corresponding to different frozen-bit sequences to improve the decoding speed of polar codes. Implementing them achieves significant latency reduction without tangibly altering the bit-error-rate performance of the code.
