A Converse Bound via the Nussbaum-Szkoła Mapping for Quantum Hypothesis Testing

Jorge Lizarribar-Carrillo, Gonzalo Vazquez-Vilar, Tobias Koch

Quantum hypothesis testing concerns the discrimination between quantum states. This paper introduces a novel lower bound for asymmetric quantum hypothesis testing that is based on…

Fundamental Limits of Noncoherent Massive Random Access Networks

Grace Villacrés, Tobias Koch, Gonzalo Vazquez-Vilar

This paper studies the capacity of massive random-access cellular networks, modeled as a MIMO fading channel with an infinite number of interfering cells. To characterize the symme…

Generalized Perfect Codes for Symmetric Classical-Quantum Channels

Andreu Blasco Coll, Gonzalo Vazquez-Vilar, Javier R. Fonollosa

We define a new family of codes for symmetric classical-quantum channels and establish their optimality. To this end, we extend the classical notion of generalized perfect and quas…

Error Probability Bounds for Gaussian Channels under Maximal and Average Power Constraints

Gonzalo Vazquez-Vilar

This paper studies the performance of block coding on an additive white Gaussian noise channel under different power limitations at the transmitter. Lower bounds are presented for…

Saddlepoint Approximations for Short-Packet Wireless Communications

Alejandro Lancho, Jöhan Ostman, Giuseppe Durisi +2

In recent years, the derivation of nonasymptotic converse and achievability bounds on the maximum coding rate as a function of the error probability and blocklength has gained atte…

Robust Signaling for Bursty Interference

Grace Villacrés, Tobias Koch, Aydin Sezgin +1

This paper studies a bursty interference channel, where the presence/absence of interference is modeled by a block-i.i.d.\ Bernoulli process that stays constant for a duration of $…
