Abstract

The impact of a fading dip in a radio channel (505) on the communication between a first (501) and a second (502) antenna may be reduced by receiving (802) a sounding signal at the first antenna or the second antenna over the radio channel and measuring (803) the frequency response of the radio channel using this sound signal that was received. The radio frequency signal that is used to communicate between the first antenna and the second antenna is adjusted {804) in response to the frequency response that was measured in order to reduce an impact of the fading dip in the radio channel on the radio frequency signal during operation. Related systems methods and devices are disclosed
