Questions (3)
We know that the eavesdroppers are malicious nodes and they are not supposed to cooperate with the users. If we exploit opportunistic relaying protocol for the destination, can we consider the same protocol for the eavesdropper? If so, then how the CSI of the eavesdropper can be estimated at the relay?
Wireless channels may be constantly and exponentially correlated (I'm interested about antenna correlation only). Actually what is the difference between these two correlations?
I want to generate a Rician-k fading SIMO channel in MATLAB to compare the analytical results with Monte-Carlo Simulation for various values of K (Rician factor).
