3 Receiver Fade

Receiver testing: the importance of fading

July 27, 2022
Learn more on things to consider and how to account for effects when testing real-world signals that may be scattered, reflected, and otherwise distorted due to time delays, phase shifts, amplitude changes, or Doppler shifts.

Typically, components and receivers are tested in a lab environment under ideal conditions. A signal propagates through the air along multiple paths between the transmitter and the receiver. The direct LOS signal often has the highest power level when it reaches the receiver. However, in the real world, scattered, reflected, and distorted signals will arrive with channel impairment. This paper focuses on how we can account for these effects during the testing and characterization of a receiver.
