Question

Which of the following option cannot be employed to overcome fading?

(a) Reduced channel symbol rates

(b) Diversity transmission and reception

(c) Decreased bandwidth

(d) Structured data

This question was addressed to me by my school principal while I was bunking the class.

The query is from Antenna Tradeoffs in section Technology Tradeoffs in Software Defined Radio of Cognitive Radio

Answer 1

Right answer is (c) Decreased bandwidth

For explanation I would say: Increased instantaneous bandwidth for multipath resolution and equalization can mitigate the effect of fading. The reduction of channel symbol rate can reduce intersymbol interference. Diversity transmission and reception, and structuring of data provide resilience against fading.
