• The outage probability of femtocell network under co-channel aggregated interference is derived in closed form.
• The capacity of femtocell network under co-channel aggregated interference is derived in closed form.
• The symbol error probability of femtocell network under co-channel aggregated interference is derived in closed form.
• The asymptotic expressions of outage probability and symbol error probability of femtocell network are obtained in detail.
• A new access mechanism to maximize the energy efficiency is proposed and its performance is further evaluated analytically.
In this paper, we will provide the performance analysis of a small cell network employing linear precoding at the base stations. The locations of the base stations are assumed to be Poisson distributed. Exact closed-form expressions for overall outage probability (OOP), symbol error probability (SEP) and capacity are derived, and an asymptotic approximation for both metrics are also investigated. Later numerical results will verify the accuracy of our analysis results. Moreover, we also propose a new access mechanism to maximize the system energy efficiency, and then evaluate the system performance analytically. Both theoretical and numerical results will together show that our proposed mechanism can improve the energy-efficiency of the small cell heterogeneous network effectively.
