Abstract

This paper proposes a correlation based double directional stochastic model (CBDDSM) for indoor Multiple Input Multiple Output (MIMO) Ultra Wideband (UWB) propagation channels in the passband domain. Both angle of arrival (AoA) and time of arrival statistics are taken into account in the modelling procedure. Spatial correlations are introduced into the amplitude matrices and delay matrices of the channel model. Under the assumption of Rayleigh amplitude fading statistics, each amplitude matrix is obtained from the underlying correlated complex Gaussian matrix, while each delay matrix is obtained as the sum of a reference matrix and a difference matrix. Model parameters are determined based on well-known measurement campaigns. Simulation results show that the characteristics of the proposed model are compatible with those of the IEEE 802.15.3a standard model. In addition, our initial analysis indicates that this model yields desirable spatial correlation properties in both the time and frequency domains.
