Question

When symbol time is much smaller than the delay spread, the resulting wireless channel is known as


​

Answer 1

In telecommunications, the delay spread is a measure of the multipath richness of a communications channel. ... The shorter the delay spread, the larger is the coherence bandwidth.

Answer 2

Answer:

• When 'symbol time' is much more smaller than the "delay spread", the "resulting wireless channel" is called as a "flat fading channel".
• When the signal traversing is much more than the given bandwidth of the system, the signal sometimes over powers the bandwidth given in a system and it can’t be traversed in the channel in a special condition and calling it as the flat fading channel.
