Abstract
A transceiver transmits first and second signals on first and second transmit radio frequencies. After detecting a received signal, intermodulation distortion caused by transmission of the first and second signals is suppressed, reduced, and/or eliminated using information associated with the first and second transmitted signals. More specifically, the information associated with the first and second transmitted signals is used to calculate or otherwise obtain a correction factor that corresponds to the intermodulation distortion. The correction factor is subtracted from the received signal to suppress the intermodulation distortion.
