A method for operating a communication device so as to mitigate intermodulation interference to a signal, includes the steps of: (i) continuously monitoring a plurality of communication channels by the communication device 604; (ii) using a noise floor level estimate of the communication device to detect when the communication device is under an influence of high interference 606; (iii) determining an optimal level of attenuation to be applied by a variable attenuator of the communication device's receiver so as to mitigate the influence of intermodulation interference doe to an interference signal 608; and (iv) selectively adjusting an amount of attenuation being applied by the variable attenuator to achieve the optimal level of attenuation 610. MethodBei 62 6006: Continuously monitoring a channel, and receiving noise and/or signals at a Communication Device ("CD") 604 Detect when the CD is under the influence of IM interference based on a noise floor level of the CD 606 Determine an optimal level of attenuation to be applied by a Variable Attenuator ("VA") prior to the front end hardware 608 Selectively adjusting an amount of attenuation being applied by the VA based on the optimal level of attenuation 610 End or perform othe6r2 processing
