Dynamic Interference Optimization in Cognitive Radio Networks for Rural and Suburban Areas

Figure 4

Emulation scenario model. The solid line defines the coverage edge of the broadcasting transmitter for 90% of locations covered, 99% of the time, the dashed line defines the limit of the broadcasting transmitter protection contour for the worst-case interference, and the dotted lines represent the extension of the broadcasting transmitter protection contour as a result of the algorithm optimization gain for the interference KPI. The diamond markers represent possible LTE-A devices reusing the same frequency .
