Abstract
An improvement is introduced of the modified successive-cancellation (MSC) decoding for polar codes, in which local decoders at rate-other nodes are simplified. This improvement reduces the decoding latency and complexity of the MSC decoding with no sacrifice in error performance. Furthermore, in our method, the decoding latency decreases rapidly with increasing signal-to-noise ratio. Significant latency and complexity reductions are shown by simulation results.
