摘要
A system and method for arbitrating among frequency-hopping spread spectrum communication systems are provided herein. An arbitrator calculates and compares (306) hop frequencies for the communication systems of an area or network using frequency generation parameters received (302) from the communication systems. The comparison identifies (308) impending transmission collisions and collision frequencies for transmission time slots. The arbitrator then selects (310) one of the radios associated with an impending collision to transmit, and suppresses or disables transmissions by non-selected radios during the same transmission time period for that frequency. Thus, the arbitrator minimizes bandwidth lost to co-channel and adjacent channel collisions by reducing or eliminating this mutual interference among the communication systems.
