Fadding means variation in the signal received at the receiver.
There are various types of fadding as described below
Selective fadding more prevalent for higher frequencies
Interference fadding: produced by the interference between upper and lower rays of the sky wave.
Absorption fadding: It occurs due to variations of signal strength with the different amount of absorption of waves absorbed by transmission.
Polarization fadding: occurs due to change in polarization of the down commingled sky waves.
Skip fadding:oocurs at distance near the skip distance.
