What are the effects of delay spread?

Frequency-selective fading caused by multipath time delay spread degrades digital communication channels by causing intersymbol interference, thus resulting in an irreducible BER and imposing a upper limit on the data symbol rate.

How to Calculate Delay Spread?

Delay Spread calculator uses Delta Spread = 1/(2*3.14*Coherence bandwidth) to calculate the Delta Spread, The Delay Spread formula is defined as In the mobile radio environment, as a result of the multipath reflection phenomenon, the signal transmitted from a cell site and arriving at a mobile unit will be from different paths. Delta Spread is denoted by Δ symbol.
