Improper Gaussian Signaling for the -user MIMO Interference Channels with Hardware Impairments
Mohammad Soleymani, Ignacio Santamaria, Peter J. Schreier
This paper investigates the performance of improper Gaussian signaling (IGS) for the -user multiple-input, multiple-output (MIMO) interference channel (IC) with hardware impairm…
Multiple Importance Sampling for Efficient Symbol Error Rate Estimation
Víctor Elvira, Ignacio Santamaría
Digital constellations formed by hexagonal or other non-square two-dimensional lattices are often used in advanced digital communication systems. The integrals required to evaluate…
Improper Signaling for SISO Two-user Interference Channels with Additive Asymmetric Hardware Distortion
Mohammad Soleymani, Christian Lameiro, Ignacio Santamaria +1
Hardware non-idealities are among the main performance restrictions for upcoming wireless communication systems. Asymmetric hardware distortions (HWD) happen when the impairments o…
Robust Improper Signaling for Two-user SISO Interference Channels
Mohammad Soleymani, Christian Lameiro, Ignacio Santamaria +1
It has been shown that improper Gaussian signaling (IGS) can improve the performance of wireless interference-limited systems when perfect channel state information (CSI) is availa…
Pattern Localization in Time Series through Signal-To-Model Alignment in Latent Space
Steven Van Vaerenbergh, Ignacio Santamaria, Victor Elvira +1
In this paper, we study the problem of locating a predefined sequence of patterns in a time series. In particular, the studied scenario assumes a theoretical model is available tha…
Recursive Multikernel Filters Exploiting Nonlinear Temporal Structure
Steven Van Vaerenbergh, Simone Scardapane, Ignacio Santamaria
In kernel methods, temporal information on the data is commonly included by using time-delayed embeddings as inputs. Recently, an alternative formulation was proposed by defining a…
