Generalized average detection probability of centralized cooperative-MIMO cognitive radio network over β — μ faded reporting channel

Abstract

In this paper a generalized closed form expression for the average detection probability of an energy detector is derived in terms of computable Meijer G-function. Where the reporting channel in the centralized cooperative spectrum sensing is experiencing a n - μ fading. The reporting network is modeled as secondary users and fusion center equipped with multiple antenna for reporting. The fusion center combines the received data using maximal ratio combining and performs energy detection to make decision. The arrived generalized low complex expression offers the different fading conditions of reporting channel. Also, it is generalized for multiple antenna scenario. The arrived expression is validated by analytical results over different n - μ values with various multiple antenna scenario.
