Research on Radio Wave Coverage of Beamforming Antennas in Train Carriage and Corridor Measurement

International Journal of Antennas and Propagation
In order to provide high-quality public mobile communication in speed train, uniform radio wave coverage in the carriage must be realized. Using repeater antenna in train carriage is an effective way to meet the requirement of radio wave coverage, but ...

Distributed Beamforming for Cognitive Radio Networks

, 2011
Cognitive radio (CR) is an approach with high potentials in the effort of battling spectrum scarcity, introduced by J. Mitola in the late 90’s. It is capable of sensing the communication environment and adapting to it by changing its radio parameters ...
