Delay Spread Solution

STEP 0: Pre-Calculation Summary

Formula Used

Delay Spread = 1/(2*3.14*Coherence Bandwidth Fading)
Δ = 1/(2*3.14*B_fad)
This formula uses 2 Variables

Variables Used

Delay Spread - (Measured in Second) - Delay Spread is a modulation technique used in CDMA systems to enable multiple users to share the same frequency band efficiently while maintaining their signal integrity and minimizing interference.
Coherence Bandwidth Fading - (Measured in Hertz) - Coherence bandwidth Fading is refers to the variation in signal strength and quality across different frequency components of a transmitted signal.

STEP 1: Convert Input(s) to Base Unit

Coherence Bandwidth Fading: 0.000156 Kilohertz --> 0.156 Hertz (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Δ = 1/(2*3.14*B_fad) --> 1/(2*3.14*0.156)

Evaluating ... ...

Δ = 1.02074146660134

STEP 3: Convert Result to Output's Unit

1.02074146660134 Second --> No Conversion Required

FINAL ANSWER

1.02074146660134 ≈ 1.020741 Second <-- Delay Spread

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 Delay Spread = 1/(2*3.14*Coherence Bandwidth Fading) to calculate the Delay 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. Delay Spread is denoted by Δ symbol.
