An omni-directional antenna array with wide band and low gain variation in the horizontal plane is proposed in this letter. The antenna unit of the array is composed of two vertically arrayed omni-directional elements and the associated feeding network. 3-D dipoles with vertical arms and parasitic dipoles are introduced in the antenna unit to significantly enhance […]

To overcome the ever increasing bandwidth demands of modern mobile radio applications, the use of spectral efficient modulation is necessary but not sufficient. Small cells are able to provide additional bandwidth at those locations where the traffic volume is high. Therefore, the number of small cells inside a larger macro-cell will be increased in the […]

Many-core embedded systems will feature an extremely dynamic workload distribution where massive applications arranged as an unpredictable sequence enter and leave the system at run-time. Efficient mapping strategy is required to allocate system resources to the incoming application. Non-contiguous mapping improves system throughput by utilizing disjoint nodes, however, the increasing communication distance and external congestion […]
