Determining the Dimension and Structure of the Subspace Correlated Across Multiple Data Sets
Tanuj Hasija, Christian Lameiro, Timothy Marrinan +1
Detecting the components common or correlated across multiple data sets is challenging due to a large number of possible correlation structures among the components. Even more chal…
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…
Improper Gaussian signaling for multiple-access channels in underlay cognitive radio
Christian Lameiro, Ignacio Santamaria, Peter J. Schreier
This paper considers an unlicensed multiple-access channel (MAC) that coexists with a licensed point-to-point user, following the underlay cognitive radio paradigm. We assume that…
Determining the Dimension of the Improper Signal Subspace in Complex-Valued Data
Tanuj Hasija, Christian Lameiro, Peter J. Schreier
A complex-valued signal is improper if it is correlated with its complex conjugate. The dimension of the improper signal subspace, i.e., the number of improper components in a comp…
Rate region boundary of the SISO Z-interference channel with improper signaling
Christian Lameiro, Ignacio Santamaria, Peter J. Schreier
This paper provides a complete characterization of the boundary of an achievable rate region, called the Pareto boundary, of the single-antenna Z interference channel (Z-IC), when…
Benefits of improper signaling for underlay cognitive radio
Christian Lameiro, Ignacio Santamaría, Peter J. Schreier
In this letter we study the potential benefits of improper signaling for a secondary user (SU) in underlay cognitive radio networks. We consider a basic yet illustrative scenario i…
Experimental Evaluation of Interference Alignment for Broadband WLAN Systems
Christian Lameiro, Óscar González, José A. García-Naya +2
In this paper we present an experimental study on the performance of spatial Interference Alignment (IA) in indoor wireless local area network scenarios that use Orthogonal Frequen…
