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 ...
