Abstract
Knowledge of the frequency hopping patterns in use by co-located frequency hopping radio systems is useful in reducing the likelihood of collisions between potentially interfering systems. Detection of the frequency hopping pattern is accomplished by determining the time interval between transmissions at a plurality of frequencies by the interfering system and by correlating the time interval to a frequency hopping pattern used by the interferer. The system type of the potentially interfering system can be determined by timing the interval between successive transmissions at a single frequency and correlating this interval or hop pattern duration to a system identifier. Many frequency hopping radio systems can carry out these methods without additional hardware.
