Simulation of Small-Scale Fading in Mobile Channel Models for Next-Generation Wireless Communications

Abstract

Small-scale fading strongly affects the performance of a radio link; therefore radio channel simulation tools and models are broadly being used in order to evaluate the impact of fading. Furthermore, channel simulation tools and models are considered to be of utmost importance for efficient design and development of new products and services for Next Generation (Wireless) Networks (NGNs and NGWNs). In this chapter, a brief description of the most popular and broadly accepted mobile radio channel models and simulation techniques is given, mainly with respect to small-scale fading. In addition, certain research results on radio channel simulation are presented. The authors hope that the information provided herein will help researchers to acquire an insight to small-scale fading simulation techniques, which will be useful for a solid understanding of the underlying physical layer properties of NGWNs.
