Abstract
Systems and methods for providing mitigation of interference in a CDMA cellular network caused by excessive in band energy are disclosed. In the preferred embodiment, multiple narrow antenna beams are used to isolate the excessive energy from that of signals from mobile units. Control circuitry measures the power level on each of these multiple beams, compares this measurement to an estimated number of mobiles operating in the associated antenna beam, and determines if excessive energy is present in the beam. If excessive energy is determined to exist, the present invention causes the gain of particular antenna beams to be adjusted so as to mitigate the effect of the excessive energy.
