English abstract:
Abstract-In this work we introduce a novel metric for characterizing the double-directional propagation environment and use this metric to assess the performance of a SAGE parameter estimator for MIMO channels. Using the IlmProp, a geometry-based MIMO channel model, we construct synthetic channels for three different scenarios showing: (i) well separated, dense clustered propagation paths with single-bounce scattering, (ii) clustered propagation paths which are spread wider, (iii) no clusters and double-bounceonly reflections. We model the scatterers and the Rx in the environment as fixed, but the Tx as moving. The Initialization and Search-Improved SAGE estimation tool is used to extract the propagation paths from the constructed channels. Both true and estimated paths are fed to the new system-independent metric which genuinely reflects the structure of the channel and the compactness of propagation paths. We use this metric to decide on the accuracy of the channel estimator. The results show a convincing conformance between true and estimated paths.
