This detection task is challenging, since the wireless environment often results in very low SNR conditions. Moreover, calibration errors and imperfect analog components at the CR spectral monitor result in uncertainties in the noise spectrum, making the problem more difficult. In this work, we present a new multiantenna detector which is based on the fact that the observation noise processes are spatially uncorrelated, whereas any primary signal present should result inspatial correlation. In particular, we derive the generalized likelihood ratio test (GLRT) for this problem, which is given by the quotient between the determinant of the sample covariance matrix and the determinant of its block-diagonal version. For stationary processes the GLRT tends asymptotically to the integral of the logarithm of the Hadamard ratio of the estimated power spectral density matrix. Additionally, we present an approximation of the frequency domain detector in the low SNR regime, which results in computational savings. The performance of the proposed detectors is evaluated by means of numerical simulations, showing important advantages over existing detectors.","lang":"eng"}],"_id":"40848","user_id":"43497","doi":"10.1109/ICASSP.2010.5496151","year":"2010","status":"public","title":"Multiantenna Spectrum Sensing: Detection of Spatial Correlation Among Time-Series With Unknown Spectra","author":[{"full_name":"Ramírez, D.","last_name":"Ramírez","first_name":"D."},{"last_name":"Vía","first_name":"J.","full_name":"Vía, J."},{"last_name":"Santamaría","first_name":"I.","full_name":"Santamaría, I."},{"first_name":"R.","last_name":"López-Valcarce","full_name":"López-Valcarce, R."},{"full_name":"Scharf, L.

Unlike the case of complex vectors, there exist three different kinds of quaternion properness, which are based on the vanishing of three different complemen- tary covariance matrices. The different kinds of properness have direct implications on the Cayley–Dickson representation of the quaternion vector, and also on several well-known multivariate statistical analysis methods. In particular, the quaternion exten- sions of the partial least squares (PLS), multiple linear regression (MLR) and canonical correlation analysis (CCA) techniques are analyzed, showing that, in general, the optimal linear processing is \\emph{full-widely linear}. However, in the case of jointly $\\mathbbQ$-proper or $\\mathbbC^{\\eta}$-proper vectors, the optimal processing reduces, respectively, to the \\emphconventional or \\emph{semi-widely linear} processing. Finally, a measure for the degree of improperness of a quaternion random vector is proposed, which is based on the Kullback–Leibler diver- gence between two zero-mean Gaussian distributions, one of them with the actual augmented covariance matrix, and the other with its closest proper version. This measure quantifies the entropy loss due to the improperness of the quaternion vector, and it admits an intuitive geometrical interpretation based on Kullback–Leibler projections onto sets of proper augmented covariance matrices.","lang":"eng"}],"citation":{"bibtex":"@article{Vía_Ramírez_Santamaría_2010, title={Properness and Widely Linear Processing of Quaternion Random Vectors}, volume={56}, DOI={<a href=\"https://doi.org/10.1109/TIT.2010.2048440\">10.1109/TIT.2010.2048440</a>}, number={7}, journal={IEEE Trans.\\ Inform.\\ Theory}, author={Vía, J. and Ramírez, D. and Santamaría, I.}, year={2010}, pages={3502–3515} }","chicago":"Vía, J., D.

An iterative soft compensation method is proposed to mitigate the clipping distortion, which can outperform conventional treatments. The impact of signaling schemes on the residual clipping noise power is studied via the symbol variance analysis. It is found that superposition coded modulation (SCM) can minimize the residual clipping noise power among all possible signaling schemes. This indicates that SCM-based OFDM systems are more robust to clipping effect than other alternatives when soft compensation is applied. It is also shown that a multi-code SCM scheme can further reduce the clipping effect and its overall performance can be quickly evaluated using a semi-analytical evolution method. Numerical examples are provided to verify the analysis."}],"date_created":"2023-01-30T11:52:01Z","type":"journal_article","department":[{"_id":"263"}]},{"date_updated":"2023-01-30T11:56:58Z","author":[{"full_name":"Vía, J.","first_name":"J.","last_name":"Vía"},{"full_name":"Ramírez, D.","first_name":"D.","last_name":"Ramírez"},{"full_name":"Santamaría, I.","last_name":"Santamaría","first_name":"I."},{"full_name":"Vielva, L.","first_name":"L.","last_name":"Vielva"}],"year":"2010","status":"public","title":"Improperness Measures for Quaternion Random Vectors","doi":"10.1109/MLSP.2010.5589225","user_id":"43497","_id":"40845","abstract":[{"lang":"eng","text":"It has been recently proved that the two main kinds of quaternion improperness require two different kinds of widely linear process- ing. In this work, we show that these definitions satisfy some im- portant properties, which include the invariance to quaternion lin- ear transformations and right Clifford translations, as well as some clear connections with the case of proper complex vectors. More- over, we introduce a new kind of quaternion properness, which clearly relates the two previous definitions, and propose three mea- sures for the degree of improperness of a quaternion vector. The proposed measures are based on the Kullback-Leibler divergence between two zero-mean quaternion Gaussian distributions, one of them with the actual augmented covariance matrix, and the other with its closest proper version. These measures allow us to quan- tify the entropy loss due to the improperness of the quaternion vec- tor, and they admit an intuitive geometrical interpretation based on Kullback-Leibler projections onto sets of proper augmented co- variance matrices."}],"citation":{"ieee":"J.

Basically, the problem reduces to finding the optimal transmit direction and the optimal power allocation between users to operate at any point on the boundary. We show that both optimization problems can be solved in closed form. First, exploiting the fact that any Pareto optimal pair of rates must also be Pareto optimal of a convex region defined by the channel energies, the optimal transmit direction is shown to be the principal eigenvector of a matrix. Second, the optimal power allocation is obtained by exploiting again the Pareto optimality of the sought pair of rates. Although this paper focuses on the BC, the obtained results also serve to characterize the dual multiple-access channel (MAC). Moreover, this explicit characterization of the boundary can be extended to a $K$-user system for $K>2$. Numerical examples are provided to illustrate the results of the paper, and to show the enlargement of the capacity region achieved by analog beamforming in comparison to a single-input single-output (SISO) BC."}],"place":"Beijing, China","date_created":"2023-01-30T11:52:01Z","type":"conference","department":[{"_id":"263"}]},{"volume":104,"user_id":"26263","publisher":"American Physical Society (APS)","_id":"40206","status":"public","citation":{"mla":"Schreiber, A., et al. “Photons Walking the Line: A Quantum Walk with Adjustable Coin Operations.” <i>Physical Review Letters</i>, vol. 104, no. 5, 050502, American Physical Society (APS), 2010, doi:<a href=\"https://doi.org/10.1103/physrevlett.104.050502\">10.1103/physrevlett.104.050502</a>.","bibtex":"@article{Schreiber_Cassemiro_Potoček_Gábris_Mosley_Andersson_Jex_Silberhorn_2010, title={Photons Walking the Line: A Quantum Walk with Adjustable Coin Operations}, volume={104}, DOI={<a href=\"https://doi.org/10.1103/physrevlett.104.050502\">10.1103/physrevlett.104.050502</a>}, number={5050502}, journal={Physical Review Letters}, publisher={American Physical Society (APS)}, author={Schreiber, A. and Cassemiro, K.
