Abstract [en]

The current focus on innovative spectrum policies and efficient wireless bandwidth utilization has motivated research on methods for dynamic spectrum access. By letting systems share the spectrum, trunking gains and better utilization of the bandwidth is predicted. From a technical point of view, the paradigm shift to open frequency bands implies a need to investigate and verify resulting capacity gains. In this paper, we give a general method for evaluating system capacity subject to outage probability constraints over fading channels, in an unlicensed environment with uncoordinated systems. The channel fading effects include attenuation, shadowing and multipath propagation and we end up with expressions, solved by numerical integration. The spectrum sharing is here performed by means of autonomous dynamic channel allocation (DCA), and we compare several DCA methods, e.g., maximum SIR and random DCA.
