SYSTEM AND METHOD FOR CONTROLLING INTERMODULATION INTERFERENCE
First Claim
1. A method of controlling intermodulation (IM) interference, the method comprising:
- determining if at least two transmitters are present, each transmitter assigned a separate transmit frequency;
determining when transmissions from the at least two transmitters are to overlap in time; and
initiating control steps to reduce the effects of IM interference when transmissions from the two transmitters are to overlap in time.

Abstract
In one embodiment, a method of controlling intermodulation (IM) interference is provided. The method comprises determining if an IM product spectrum overlaps the spectrum of an assigned receive frequency and determining when transmissions from at least two transmitters are to overlap in time. If the IM product spectrum overlaps the assigned receive frequency spectrum, it is determined if a signal is being propagated on the receive frequency when the transmissions from the at least two transmitters are to overlap in time. If a signal is not being propagated on the receive frequency, the at least two transmitters are allowed to transmit the overlapping transmissions; and if a signal is being propagated on the receive frequency, control steps are initiated to reduce the effects of IM interference
