The cumulative impact of co-channel interferers, commonly referred to as
aggregate network interference, is one of the main performance limiting
factors in today's mobile cellular networks. Thus, its careful
statistical description is decisive for system analysis and design. A
system model for interference analysis is required to capture essential
network variation effects, such as base station deployment- and signal
propagation characteristics. Furthermore it should be simple and
tractable so as to enable first-order insights on design fundamentals
and rapid exchange of new ideas. Interference modeling has posed a
challenge ever since the establishment of traditional macro-cellular
deployments. The recent emergence of heterogeneous network topologies
complicates matters by contesting many established aspects of
time-honored approaches. This book presents user-centric system models
that enable to investigate scenarios with an anisotropic interference
impact.
