Abstract − The availability of realistic channel models that truly capture the temporal and spatial structure of the mobile radio channel in a given propagation environment is a major requirement for the detailed performance assessment of spacetime adaptive receivers. This paper presents a novel measurement-based parametric approach for modelling the double-directional mobile radio channel. Applying a multidimensional high-resolution parameter estimation procedure, sets of descriptive parameters for any relevant propagation path in a specific scenario can be extracted from broadband multiple-input multiple-output (MIMO) channel sounding data. Then, from the estimated parameter sets a local reconstruction of the multidimensional wave fields in the vicinity of the measured aperture volumes in time, space and frequency is performed. Since the properties of the measurement antennas are excluded from the channel this way, synthetic channel impulse responses for various application-specific array architectures within the reconstructed wave fields can be derived. This builds the basis for manifold analyses and simulations of MIMO transmission links in a realistic way.
