Comparison of linear and widely linear processing in MIMO-FBMC systems
(VDE Conference Publications, 2013)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper carries out a comparison between two multi-stream techniques aimed for filter bank multicarrier (FBMC) systems based on the offset quadrature amplitude modulation (OQAM). The first option performs linear processing ... -

Wall mitigation techniques for indoor sensing within the compressive sensing framework
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
Text en actes de congrés
Accés restringit per política de l'editorialCompressive sensing (CS) for urban operations and through-the-wall radar imaging has been shown to be successful in fast data acquisition and moving target localizations. However, the research work in this area thus ... -
Diversity mdir receiver for space-time dispersive channels
(European Commission, 2000)
Text en actes de congrés
Accés obertA particular property of the cellebrated MDIR receiver is introduced in this communication, namely, the fact that full exploitation of the diversity is obtained with multiple beamformers when the channel is spatially and ... -
The RCAP: a concept for robust beamforming and high resolution DOA tracking
(IEEE Press, 2000)
Text en actes de congrés
Accés obertMotivated by the objective of finding a reduced complexity implementation of the EM (estimate and maximize) algorithm, the authors move the concept of alternating projection (AP), reported Ziskind and Wax (1988), to a ... -
Blind beamforming for DS-CDMA systems
(Servicio de Publicaciones Universidad de Vigo, 1999)
Text en actes de congrés
Accés obertCode Division Multiple Access (CDMA) has been proposed as an efficient access method for cellular and personal communication systems outperforming the classical FDMA and TDMA techniques. But, in contrast to them, CDMA ... -
Fuzzy techniques for robust localization & tracking
(GRETSI SERVICE, 1997)
Text en actes de congrés
Accés obertThis work addresses the problem of spatial reference estimation in mobile scenarios. Novel techniques based on fuzzy logic are introduced to enhance the performance of a tracking system. Specifically, the model-free ... -

Experimental result for a sdma mobile communications antenna array system
(EE PUBL. EE PUBL., 1996)
Text en actes de congrés
Accés obertThis paper presents experimental results for a Spatial Division Multiple Access cellular mobile communications system. The basestation antenna array testbed used to obtain the results is described in addition to sophisticated ... -
High performance doa trackers derived from paralell low resolution detectors
(IEEE, 1996)
Text en actes de congrés
Accés obertTraditionally, high resolution spectral direction of arrival (DOA) estimation has been associated with algorithms rather than with a processing scheme or architecture. Motivated by previous work on feasible implementations ... -
High resolution adaptative arrays based on random processing techniques: frequency hopping modulation
(Institute of Electrical and Electronics Engineers (IEEE), 1995)
Text en actes de congrés
Accés obertA new architecture for adaptive arrays using frequency hopping modulation is addressed. The resolution of the array and the interference rejection increase substantially applying random processing to the carrier frequency ...
