An ultra-wideband space-variant multipath indoor radio channel model

Abstract

We present a generic ultra-wideband (UWB) multipath radio channel model that has been designed for link-level simulations and is suited for indoor environments, e.g. for WPAN applications. It covers the FCC frequency band [FCC, Feb. 2002] and is capable of producing space-variant impulse responses (IR) and transfer functions. The model is of a hybrid type and combines a statistical approach to model dense multipath and a simple quasi-deterministic method to model strong individual echoes. These echoes are important to obtain a realistic spatial (Doppler) behavior. The architecture of the model facilitates the application to UWB MIMO analyses. For a few scenarios (e.g., intra-office and inter-office transmission), site-specific parameter profiles are given that have been derived from measured data.
