This paper investigates high order NonUniform Constellations (NUC) with constellation sizes of up to 4K-QAM for broadcasting over-the-air very high data rate services such as Ultra-High Definition TV (UHDTV). An iterative algorithm is proposed for fast convergence towards the optimal NUC at each Signal-to-Noise Ratio (SNR) operating point. Performance evaluation assuming DVB-T2 as a reference shows significant gains for NUC over uniform constellations, above 1 dB for orders higher than 256-QAM… Expand
Non-Uniform Constellations for ATSC 3.0

Low-Complexity Demapping Algorithm for Two-Dimensional Non-Uniform Constellations
A demapping algorithm is proposed that reduces from 69% to 93% the number of required distances when using 2D-NUCs, and discards or replicates those constellation symbols that provide scarce information, with a performance degradation lower to 0.1 dB compared to the optimal maximum likelihood demapper.

This work addresses the problem of finding the signal sets that are the most suitable for designing power-efficient BICM schemes over an additive white Gaussian noise (AWGN) channel, and shows that the most attractive signal sets are those for which Gray mapping is possible, provided that their symbol error rate performance is "sufficiently close" to the optimum.
