Uplink capacity and interference avoidance for two-tier femtocell networks
Uplink capacity and interference avoidance for two-tier femtocell networks
Two-tier femtocell networks- comprising a conventional cellular network plus embedded femtocell hotspots- offer an economically viable solution to achieving high cellular user capacity and improved coverage. With universal frequency reuse and DS-CDMA transmission however, the ensuing cross-tier interference causes unacceptable outage probability. This paper develops an uplink capacity analysis and …
