Abstract
Systems and methods for automatic frequency coordination are provided. In one embodiment, an automatic frequency coordination (AFC) system for authorizing unlicensed operator utilization of a shared spectrum band comprising channels licensed to incumbent operators comprises: a processor coupled to a memory; and an exclusion zone calculator executed by the processor, the exclusion zone calculator configured to construct an exclusion zone for an incumbent receiver antenna operating on a licensed channel of the shared band, wherein the calculator is configured to construct the exclusion zone by: calculating a set of exclusion zone radiuses along a plurality of radials of a radial grid based on applying a moving average filter to interference power values calculated for a plurality of locations along a length of each of the radials; and applying an averaging filter to the exclusion zone radiuses to define the exclusion zone between the exclusion zone radiuses and the receiver antenna.
