MITIGATING INTERMODULATION INTERFERENCE USING CHANNEL POWER ESTIMATION AND ATTENUATION IN A TWO-WAY RADIO COMMUNICATIONS SYSTEM

摘要

A method for maximizing intermodulation interference protection during ahandoff between radio cell sites (300) includes scanning a plurality of radiochannels (302) and measuring the signal power (307, 315) for at least one ofthe radio channels. One or more receiver attenuators (313) are then set basedon the detection of intermodulation (IM) interference of the measured channel.The attenuators are then scaled (311) based on the degree of IM interference.If the attenuators cannot mitigate this interference below some predeterminedlevel, the radio channel is changed (321) and the process begins again toensure a high quality of communication with a cell site.
