Passive detection of a random signal common to multi-sensor reference and surveillance arrays

no code implementations12 Feb 2024 David Ramírez, Ignacio Santamaria, Louis L. Scharf

This paper addresses the passive detection of a common rank-one subspace signal received in two multi-sensor arrays.

Improper Gaussian Signaling for the $K$-user MIMO Interference Channels with Hardware Impairments

no code implementations28 Jan 2020 Mohammad Soleymani, Ignacio Santamaria, Peter J. Schreier

This paper investigates the performance of improper Gaussian signaling (IGS) for the $K$-user multiple-input, multiple-output (MIMO) interference channel (IC) with hardware impairments (HWI).

Recursive Multikernel Filters Exploiting Nonlinear Temporal Structure

no code implementations12 Jun 2017 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.

Gaussian Processes for Nonlinear Signal Processing

no code implementations12 Mar 2013 Fernando Pérez-Cruz, Steven Van Vaerenbergh, Juan José Murillo-Fuentes, Miguel Lázaro-Gredilla, Ignacio Santamaria

Gaussian processes (GPs) are versatile tools that have been successfully employed to solve nonlinear estimation problems in machine learning, but that are rarely used in signal processing.
