Abstract
A modification is introduced of the successive-cancellation decoder for polar codes, in which local decoders for rate-one constituent codes are simplified. This modification reduces the decoding latency and algorithmic complexity of the conventional decoder, while preserving the bit and block error rate. Significant latency and complexity reductions are achieved over a wide range of code rates.
