Abstract :
In this paper we analyze the performance of a small cell network where the locations of the base stations are generated according to Poisson distribution and linear multiuser precoding is employed. The performance metrics of both the overall outage probability (OOP) and the symbol error probability (SEP) are investigated for this small cell network. Tight closed-form expressions for the OOP and the average SEP are derived, and an asymptotic approximation to the OOP and the average SEP are also obtained, respectively. Their accuracy are validated via our numerical results. In addition, we propose a new access mechanism to maximize the energy efficiency and further evaluate its performance analytically. Both theoretical and numerical results show that the proposed scheme could effectively improve the efficiency of the small cell heterogeneous network.
