“…There have been few works (e.g. [30]- [33]) investigating HCPP in FD networks. In [31], [32], HCPP was used in simulations to model the locations of BSs, and its statistic characteristics were not leveraged in performance analysis VOLUME 8, 2020 of FD networks.…”

“…In [30], BSs serving one user each were assumed to distributed according to a PPP while only a subset of BSs which transmit in the same frequency band was modeled as a HCPP. In [33], a fixed number of DL users was considered, and only the capacity of users was analyzed. To the best of the author's knowledge, this paper is the first to study the performance of a general and realistic FD cellular network where FD BSs are modeled as a HCPP while DL and UL HD users are distributed according to PPPs.…”

“…1, each BS is equipped with M d transmit antennas and M u receive antennas to serve multiple DL and UL HD users in circular regions with radius R, centered around the BSs. Defer from [33], for each BS the associated DL and UL users are randomly distributed in the circular region according to PPP with intensities λ d P and λ u P respectively [34]. Furthermore, DL users, requiring b d streams each, are equipped with N d antennas; while UL users, requiring b u streams each, are equipped with N u antennas.…”

We analyze the performance of a cellular network, where Poisson point process distributed half-duplex (HD) downlink (DL) and uplink (UL) users are served by multiple full-duplex (FD) base stations (BSs). To address the surge in interference in the network due to the simultaneous operation in time and frequency of the FD BSs, we (a) adopt a self-interference cancellation scheme at each BS, and (b) apply linear interference alignment in each cell to cancel the intra-cell interference. Further, to better capture the distribution of the FD BSs, we model the BSs as a Matérn hard-core point process, in which a minimum distance is imposed between points. The performance of both UL and DL users is analyzed by deriving general expressions and closed-form approximations for the outage probability and throughput. Next, simulations are carried out for both macro and micro cell environments under both FD and HD operations with respect to various network parameters. Our results reveal several fundamental characteristics and the necessary conditions required for the successful deployment of such networks.INDEX TERMS Full-duplex communication, interference alignment, Matérn hard-core point process, stochastic geometry.

“…The study in [23] modeled the spatial distribution of transmitters as a Poisson hard-core process in wireless networks, and provided approximations of the coverage probability by employing the quasi-Monte Carlo method. The Matérn hard core point process (MHCPP) is an important type of exclusion point process, which has been used in wireless network modeling [24][25][26][27]. Although the MHCPP models the networks well, it is difficult to find the exact distribution of the signal-to-interference ratio (SIR), which is the crux to analyzing the coverage probability and achievable data rate of the networks [28][29].…”

The Poisson point process (PPP) is widely used in wireless network modeling and performance analysis because it can provide tractable results for heterogeneous cellular networks (HetNets) analysis. However, it cannot accurately reflect the spatial distribution characteristics of the actual base stations (BSs). Considering the fact that the distribution of macro base stations (MBSs) is exclusive, the deployment of MBSs is modeled by the Matérn hard-core point process (MHCPP), and the deployment of pico base stations (PBSs) is modeled by PPP. This paper studies the performance of multiantenna HetNets and improves the energy efficiency (EE) of HetNets by optimizing the transmit power of PBSs. We use a simple approximate method to study the signal-to-interference ratio (SIR) distribution in two-tier MHCPP-PPP HetNets and derive the coverage probability, average data rate and EE of HetNets. Then, an optimization algorithm is proposed to improve the EE of HetNets. Finally, three transmission technologies are simulated and analyzed. The results show that multiantenna transmission has better system performance than single antenna transmission and that selecting the appropriate transmit power for a PBS can effectively improve the EE of the system. In addition, two-tier MHCPP-PPP HetNets have higher EE than two-tier PPP-PPP HetNets.
