Downlink coverage probability in MIMO HetNets [PDF]
2012 Conference Record of the Forty Sixth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2012 The growing popularity of small cells is driving cellular networks of yesterday towards heterogeneity and randomness. Soon, hundreds of unplanned user deployed femtocells and tens of operator managed picocells will coexist in a typical macrocell. One of the natural ways to model base station (BS) locations in such heterogeneous cellular networks, or ...

Coverage Probability Analysis of UAV Cellular Networks in Urban Environments [PDF]
2018 IEEE International Conference on Communications Workshops (ICC Workshops), 2018 In this paper, we study coverage probabilities of the UAV-assisted cellular network modeled by 2-dimension (2D) Poisson point process. The cellular user is assumed to connect to the nearest aerial base station.

Coverage probability of uplink cellular networks [PDF]
2012 IEEE Global Communications Conference (GLOBECOM), 2012 The cellular uplink has typically been studied using simple Wyner-type analytical models where interference is modeled as a constant or a single random variable, or via complex system-level simulations for a given set of parameters, which are often insufficient to evaluate performance in all operational regimes.

On Coverage Probability in Uplink NOMA With Instantaneous Signal Power-Based User Ranking [PDF]
IEEE Wireless Communications Letters, 2019 In uplink non-orthogonal multiple access (NOMA) networks, the order of decoding at the base station (BS) depends on the received instantaneous signal powers (ISPs). Therefore, the signal-to-interference ratio (SIR) coverage probability for an uplink NOMA
