Performance analysis of two-layer heterogeneous cellular networks based on generalized Matern hard-core point processes

Abstract： The Generalized Matern Hard-Core Point Process (GMHCPP) is a repulsive point process that extends the hard core point process by introducing competition and thinning functions to constrain the retention probability. In this paper, we conduct an in-depth analysis of the performance of macro base stations and micro base stations within a two-layer heterogeneous cellular network model. We derive approximate expressions for the coverage probability and mean achievable throughput of this model. First, based on the performance differences and repulsive characteristics of the macro base stations, a retention probability function is derived. Subsequently, the deployment of macro base stations is modeled using GMHCPP. Then, Monte Carlo simulations are employed to simulate the base station distribution, and the relationship between the average interference-to-signal ratio and the path loss factor is plotted. From this function, the gain factor expression of GMHCPP is derived by fitting with the Poisson point process(PPP) approximation. Finally, the gain factor is incorporated into the coverage probability and mean achievable throughput formulas to simulate and analyze the performance metrics of the two-layer heterogeneous cellular network model.
