On the Dimensioning of Cellular OFDMA Networks
published in "Elsevier Physical Communication 5, 1 (2012) 10-21
Abstract
In this paper, we address the issue of cellular OFDMA networks dimensioning.
Network design consists of evaluating cell coverage and capacity and
may involve many parameters related to environment, system configuration,
and quality of service (QoS) requirements. In order to quickly study the
impact of each of these parameters, analytical formulas are needed. The
key function for network dimensioning is the Signal to Interference Ratio
(SIR) distribution. We thus analyze in an original way the traditional issue
of deriving outage probabilities in OFDMA cellular networks. Our study
takes into account the joint effect of path-loss, shadowing, and fast fading
effects. Starting from the Mean Instantaneous Capacity (MIC), we derive the
effective SIR distribution as a function of the number of sub-carriers per subchannel.
Our formula, based on a fluid model approach, is easily computable
and can be obtained for a mobile station (MS) located at any distance from
its serving base station (BS). We validate our approach by comparing all
results to Monte Carlo simulations performed in a hexagonal network, and
we show how our analytical study can be used to analyze outage capacity,
coverage holes, and network densification. The proposed framework is a powerful
tool to study performances of cellular OFDMA networks (e.g. WiMAX,LTE).
