What is the effect of multipath fading on the received signal?
In a multipath fading environment, the relative motion between the transmitter and receiver may also cause broadening of the power spectrum. Additionally, the wireless channel, or the over-the-air link between a transmitter and a receiver, is subject to interference from other users in the system.
How does multipath propagation contribute to fading?
Destructive interference causes fading; this may cause a radio signal to become too weak in certain areas to be received adequately. For this reason, this effect is also known as multipath interference or multipath distortion.
What are the effects of multipath propagation?
Multipath propagation, an inherent feature of a mobile communications channel, results in a received signal that is dispersed in time. Each path has its own delay and the time dispersion leads to a form of intersymbol interference. Delay spread is a measure of the multipath profile of a mobile communications channel.
