Bit-Interleaved Polar-Coded Modulation for Low-Latency Short-Block Transmission

Abstract

We show that polar codes with list+CRC decoding can outperform state-of-the-art LDPC codes in short block lengths. In addition, we introduce an efficient interleaver for polar-coded high-order modulations, achieving greater than 0.5 dB gain for 256QAM.
