Antenna subset selection for cyclic prefix assisted MIMO wireless communications over frequency selective channels

Wilzeck, A.; Kaiser, T. (Heidelberg : Springer Verlag, 2008)

Antenna (subset) selection techniques are feasible to reduce the hardware complexity of multiple-input multiple-output (MIMO) systems, while keeping the benefits of higher-order MIMO systems. Many studies of antenna selection ...
Correlation properties of dual polarized antennas with finite pattern orthogonality in mobile fading channels

Armbrecht, G.; Klemp, O.; Rolfes, I. (Göttingen : Copernicus GmbH, 2007)

Starting from planar broadband log.-per. antenna design, offering the possibility of dual-polarized reception properties, in this article a generalized mathematical approach for rapidly estimating the resulting signal ...
Neural sensing and control in a kilometer-scale gravitational-wave observatory

Mukund, N.; Lough, J.; Bisht, A.; Wittel, H.; Nadji, S.; Affeldt, C.; Bergamin, F.; Brinkmann, M.; Kringel, V.; Lück, H.; Weinert, M.; Danzmann, K. (College Park, Md. [u.a.] : American Physical Society, 2023)

Suspended optics in gravitational-wave (GW) observatories are susceptible to alignment perturbations, particularly slow drifts over time, due to variations in temperature and seismic levels. Such misalignments affect the ...
On the performance of the time reversal SM-MIMO-UWB system on correlated channels

Nguyen, Hieu; Nguyen, Van Duc; Nguyen, Trung Kien; Maichalernnukul, Kiattisak; Zheng, Feng; Kaiser, Thomas (New York, NY : Hindawi Publishing Corporation, 2012)

The impact of spatial correlation on the multi-input multi-output ultrawide band (MIMO-UWB) system using the time reversal (TR) technique is investigated. Thanks to TR, several data streams can be transmitted by using only ...
Optical fibre sensors based on multi-mode fibres and MIMO signal processing: An experimental approach

Ahrens, Andreas; Sandmann, Andre; Bremer, Kort; Roth, Bernhard; Lochmann, Steffen (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)

In this paper multiple-input multiple-output (MIMO) signal processing is investigated for fibre optic sensor applications. A (2 × 2) MIMO implementation is realized by using lower-order and higher-order mode groups of a ...
Radiation pattern analysis of antenna systems for MIMO and diversity configurations

Klemp, O.; Eul, H. (Göttingen : Copernicus GmbH, 2005)

Multiple-input multiple-output (MIMO) antenna systems and antenna configurations for wideband multimode diversity rank among the emerging key technologies in next generation wireless communication systems. The analysis of ...
Spherical mode analysis of planar frequency-independent multi-arm antennas based on its surface current distribution

Armbrecht, G.; Klemp, O.; Eul, H. (Göttingen : Copernicus GmbH, 2006)

Deployment in the design of mobile radio terminals focuses on the implementation of multiradio transmission systems, using a multiplicity of different radio standards combined with high-speed data communication over ...
