Multi-antenna techniques capable of exploiting the elevation dimension are anticipated to be an important air-interface enhancement targeted to handle the expected growth in mobile traffic.
Recently there have been proposals to extend MIMO processing to the elevation dimension in addition to the azimuth direction. To accurately assess the promised gains of these ?3D-MIMO?
This paper reports the results from our latest field measurement campaign for characterizing the 3-dimensional (3D) MIMO channel, particularly in the elevation domains, in a typical urban macro (UM
There is growing interest in using millimeter wave (mmWave) frequencies for future access communications based on the enormous amount of available spectrum.
In the context of 3D watermarking, most of the state-of-the-art techniques analyze a 3D/3D approach where the insertion and the extraction of the mark take place over the object itself, whereas the
This paper describes the ALCATEL experience on the design, manufacturing and measurement of microwave and digital modules based on 3D packaging approach.
Diffractive optical elements such as hyperbolic lens and quasi-spherical lens converting a divergent terahertz beam into the focal line segment perpendicular to the optical axis was designed.
Many modern applications and window systems perform 3D rendering.
We tackle two practical problems in robotic scene understanding: first, the computational requirements of current semantic segmentation algorithms are prohibitive for typical robots; and second, th
We present a geometry-based indexing approach for the retrieval of video databases.
