Question

Which parameter can be used to compute the permissible power of xG users?

(a) Distance between the primary transmitter and xG user

(b) Amount of interference at the primary receiver

(c) Amount of interference at xG user

(d) Distance between the primary receiver and xG user

I have been asked this question at a job interview.

Asked question is from Next Generation Wireless Network in division Next Generation Wireless Network of Cognitive Radio

Answer 1

Right choice is (b) Amount of interference at the primary receiver

The explanation: Channel capacity can be estimated by determining the permissible power of an xG user. The permissible power is computed by determining the amount of interference at the primary receiver. The amount of interference sometimes depends on the number of users in the spectrum.
