N2 - In the last years the use of multiple receive antennas as well as multiple transmit antennas has attracted worldwide attention to extend existing mobile communication systems with respect to their performance. Therefore it is of great importance to know the features of the real propagation channel. To this end, the real propagation channel is investigated by MIMO Channel Sounding, where high-resolution parameter estimation schemes are used to resolve the physical channel with respect to their spatial (and temporal) structure. However, due to narrow diffuse scatterers the commonly used model of discrete wavefronts is no longer valid. In this article we introduce a simple approach to model wavefronts with small angular spread. Additionally, we show that the ESPRIT algorithm with a slight modification is applicable to jointly estimate the direction of arrival and the angular spread. The approach is based on the assumption of Gaussian distributed wavefronts.
