Modelling, Performance Analysis and Design of WPAN Systems

Abstract

Abstract. This paper covers the main issues that must be solved in order to design and analyse the performance of Wireless Personal Area Networks (WPANs) with the aid of simulation tools. We review state-of-the-art channel models to account for small-and large-scale propagation conditions in waveform-and system-level simulations. When dealing with waveform simulations, we also look at Montecarlo and importance sampling techniques that allow efficien estimation of error probabilities. Additionally, discrete channel models are introduced to efficientl link both waveform-and system-level approaches and we point out some methods to obtain the model parameters that are suitable for the wireless environment. The discussion of these techniques is complemented with two application examples that show the use of the different simulation levels for system design and performance study. With the paradigm of Bluetooth piconets we illustrate the usefulness of discrete channel models and we consider the design of an OFDM-based WPAN system to exemplify simulation from a waveform-level point of view.
