  • Communication system that avoids co-channel interference
    Patent number: 5319796
    Abstract: Co-channel user (129) interference on trunked radio communication systems cannot be compensated for in the same way as conventional radio systems because the communication unit does not know what frequency it will be assigned to until it begins transmitting. Placing an additional receiver (119) in the coverage area (125) of the co-channel user (129) and sending information of recent co-channel usage to the controller (101) allows the controller (101) to decide which channel has the least likelihood of co-channel interference so that it may be assigned.
