Abstract:A bit-interleaved coded modulation (BICM) scheme with iterative (soft) demapping and decoding (IDD) is developed for non-coherent communication over a multipleinput multiple-output (MIMO) channel. The scheme exploits the underlying Grassmannian geometry of the signalling scheme that approaches the ergodic capacity of the noncoherent model at high signal-to-noise ratios. This geometry guides the construction of the MIMO constellation and gives rise to a computationally-efficient list-based demapping algorithm. … Show more
