Delayed Bit-Interleaved Polar Coded Modulation with Superposition Gray Labeling

We present a delayed bit-interleaved polar coded modulation (D-BIPCM) scheme. Particularly, we consider uniform quadrature amplitude modulation (QAM) and without iterative detection and decoding. We propose a superposition constellation labeling, which treats an M-QAM constellation as the superposition of two Gray-labeled QAM constellations of smaller sizes. The delay indices for D-BIPCM are then ...
