Coherence Bandwidth and Coherence Time

This page on Coherence Badwidth vs Coherence time describesdifference betweenCoherence Bandwidth and Coherence Time.

Coherence Bandwidth

Bandwidth (range of frequencies) over which channel is constant is calledcoherence Bandwidth.

Coherence Bandwidth ~ (1/Maximum Delay Spread)

The better way to calculatecoherence bandwidthis using RMS Delay Spread, as different channel will experience different signal intensity over different delay span with same delay spread.

Coherence Bandwidth

Coherence Time

Time over which channel is constant is calledcoherence time.
Coherence Time
