Abstract

In this paper, we consider the average secrecy capacity of a single-input multiple-output (SIMO) system with channel estimation error over generalized fading channels in the presence of co-channel interference and an eavesdropper. More specifically, we assume that selection combining is applied at both the receiver and eavesdropper. We first present statistical analysis for the signal-to-interference plus noise ratio (SINR). Then, closed-form expressions for the average secrecy capacity are derived for two special cases: Rayleigh fading and no interference. For the general case, we focus on the asymptotic secrecy capacity analysis. Finally, numerical results are provided for average secrecy capacity with with different values of N and N. Results show that the scaling law of the secrecy capacity is 1/L log (N /N).
