Abstract :
The present paper incorporates the impact of adaptive downlink power control in modern satellite communication networks on the broadband wireless access networks. DVB-S2 and WiMax standards specify the employment of adaptive power control as fade mitigation technique at frequencies above 10 GHz. The subject of this paper is to furnish a physical model for the examination of the increased interference due to satellite downlink power control to WiMax terminals. To quantify the interference effects, the carrier-to-interference ratio (CIR) statistics of WiMax link is being calculated. Extended numerical are presented and finally some useful conclusions regarding the spectral coexistence of WiMax and DVB-S2 networks are drawn.
