A PDF based approach for average detection probability of energy detector over ν — μ faded cooperative-MIMO reporting channel

Abstract

In this paper, we originated a closed form analytical expression for the average detection probability of the energy detector at the fusion centre (FC) with multiple antenna utilizing probability density function (PDF) approach. We consider an i.i.d ν — μ fading channel for providing details regarding the centralized cooperative MIMO-cognitive radio (CR) network. Every secondary users (SU) and FC furnished with multiple antenna for reporting. Using maximal ratio combining (MRC) technique FC combines the received signal and performs energy detection to make a decision. The obtained analytical expression can be utilized for the distinctive fading models as an exceptional instances of reporting channel. Additionally, it is generalized for multiple antenna situation. The arrived expression is Substantiated by analytical results over various ν — μ values with different multiple antenna scenario.
