Question

Which among the following may be implemented to reduce the amount of assumption about interference?

a.

Installing multiple sensors to observe the same transmission

b.

Developing multiple channel models

c.

Developing multiple signal propagation models

d.

Installing multiple resource managers

Posted under Cognitive Radio

Answer: (a).Installing multiple sensors to observe the same transmission Explanation:The removal of uncertainty can reduce the required amount of power at the cognitive transmitter with the certainty of non-interference to the victim receiver. Although multipath scenarios cannot be eliminated, installing multiple sensors to observe the same transmission can reduce the amount of assumption about interference.
