Systems, methods and devices for reducing impact of fading dips on radio channels

摘要

The impact of a fading dip in a radio channel on the communication between a first and a second antenna may be reduced by receiving a sounding signal at the first antenna or the second antenna over the radio channel and measuring 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 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.

1. A method of reducing an impact of a fading dip in a radio channel between a first antenna and a second antenna, the method comprising:
receiving a sounding signal at the first antenna or the second antenna over the radio channel; measuring a frequency response of the radio channel using the sounding signal that was received; and adjusting, in response to the measuring of the frequency response, a carrier frequency for transmission of a radio frequency signal in the radio channel that is used to communicate between the first antenna and the second antenna, to reduce an impact of the fading dip in the radio channel on the radio frequency signal.
