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

Posted under Cognitive Radio

Answer: (b).Amount of interference at the primary receiver 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.
