| Popis: | With the development of large-scale integrated circuits and Internet, 5G has become the hot topic of current mobile communication. Device-to-device communication (D2D) is one of the key technologies of 5G. In this paper, considering the in-band communication, we use the Poisson cluster process (PCP) to model and analyze the heterogeneous cellular and D2D networks. Firstly, we use the Thomas cluster process to model cellular users and D2D users. Secondly, we analyze the aggregated interference of the typical D2D receiver in the heterogeneous cellular and D2D networks. Then we analyze the Laplace transform of the aggregated interference and deduce the coverage probability of the typical D2D receiver. Simulation results show that the path loss exponent and D2D users' distribution density have significant influence on the performance of heterogeneous cellular and D2D networks. Compared with the grid model and PPP model, PCP model can realize the performance optimization of the clustered D2D networks. |
