Question

Diffracted propagation undergoes attenuation at the rate of the third power of distance.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Posted under Cognitive Radio

Answer: (a).True Explanation:Cognitive radio shifts communication from direct propagation to diffracted propagation. Diffracted propagation undergoes attenuation at the rate of the fourth power of distance. It hinders the ability of the radio to sense, calculate interference, and evaluate the outcome of communication.
