An antenna of a base station, it has some sectors. The vertical communicates with mobile phones, the round one connects the base station with a controller.
For example, if a controller has communicated with a particular aircraft several times, s/he will be more likely to remember "seeing"that aircraft and less likely to remember another aircraft that traversed the sector with little communication.
An apparatus and method having a de-interleaving memory and a controller is used for de-interleaving interleaved data in a coded orthogonal frequency division multiplexing receiver.
A technique to constrain controller dimension a priori in the design process employing a controller canonical realization and a homotopy algorithm is used to design fixed order H_∞ controllers.
If United flight 27enters a controller's airspace at 11:0every morning, she expects to see that aircraft show up at that time.
Aircraft now move across a controller's green radar screen as a blip of light.
