Abstract : A discussion of the critical parameters causing distortion due to multipath in a VHF-FM data link is presented. Such parameters as time delay, relative amplitude between signals, index of modulation, and modulating frequency are discussed. The effect of varying each of these parameters is demonstrated and bounds on each parameter are established. Some analytical arguments are presented to give an insight into the multipath mechanism.
