|What is Dispersive Fade Margin (DFM)?|
|Answer:1.The sensitivity of digital radio equipment to frequency-selective fading can be described by the signature curve of the equipment.|
2.This curve can be used to calculate the Dispersive Fade Margin (DFM).
3.currently radios are very robust and immune to spectrum- distorting fade activity. Only a major error in path engineering (wrong antenna or misalignment) over the high-clearance path could cause dispersive fading problems
