How does frequency selective fading differ from flat fading?
Flat Fading is caused by absorbers between the two antennae and is countered by antenna placement and transmit power level. Frequency selective fading is caused by reflectors between the transmitter and receiver creating multi-path effects.
What is the effect of frequency selective fading?
A consequence of frequency selective fading is intersymbol interference where symbols received over the direct or the shortest reflecting paths are interfered with by previous symbols arriving at the same time over longer delay paths.
What do you know about frequency selective fading explain in details?
Selective fading or frequency selective fading is a radio propagation anomaly caused by partial cancellation of a radio signal by itself — the signal arrives at the receiver by two different paths, and at least one of the paths is changing (lengthening or shortening).
What is flat fading?
1. A type of small scale fading where all frequency signal components experience the same magnitude of fading; corresponds to the case where the signal bandwidth is smaller than the channel coherence bandwidth.
