High-SNR Asymptotics of Mutual Information for Discrete Constellations with Applications to BICM
Alex Alvarado, Fredrik Brannstrom, Erik Agrell +1
Asymptotic expressions of the mutual information between any discrete input and the corresponding output of the scalar additive white Gaussian noise channel are presented in the li…
The Capacity Loss of Dense Constellations
Tobias Koch, Alfonso Martinez, Albert Guillén i Fàbregas
We determine the loss in capacity incurred by using signal constellations with a bounded support over general complex-valued additive-noise channels for suitably high signal-to-noi…
Diversity versus Channel Knowledge at Finite Block-Length
Wei Yang, Giuseppe Durisi, Tobias Koch +1
We study the maximal achievable rate R*(n, ε) for a given block-length n and block error probability εover Rayleigh block-fading channels in the noncoherent setting and in the fini…
At Low SNR Asymmetric Quantizers Are Better
Tobias Koch, Amos Lapidoth
We study the capacity of the discrete-time Gaussian channel when its output is quantized with a one-bit quantizer. We focus on the low signal-to-noise ratio (SNR) regime, where com…
