ABSTRACT:
A method for identifying interferers in a radio communication band, such as the 2.4 GHz ISM band, uses a priori information of the interferers such as channel structure, channel frequency and channel bandwidth. Measured RSSI can be used to detect and identify interferers. RSSI measurements can be made at multiple frequencies within a channel of the interferer. Randomization of RSSI measurements improves the likelihood of interferer detection and identification if such interferer is present. Metrics other than RSSI can be used.
