In this paper, an adaptive subcarrier allocation scheme with reconfiguration of operating parameters for Cognitive Radio Networks (CRN) is presented. A QoS-cons
Fractal antennas are characterized by space filling and self-similarity properties which results in considerable size reduction and multiband operation as compa
A novel approach for improving antenna bandwidth is described using a 6-element Yagi-Uda array as an example. The new approach applies Central Force Optimizatio
