A generic wideband channel model for keyhole propagation scenarios and experimental evaluation

In this contribution we propose a geometry-based generic model to characterize a propagation channel in a keyhole environment. The channel considered is dispersive in delay, direction of departure, direction of arrival, and Doppler frequency. Based on the model, we derive the analytical expressions of the marginal and conditional dispersion of the channel, the correlation matrix and the power spectral density of the channel. Experimental characteristics obtained in a indoor environment justifies the applicability of the model in describing the dispersive behavior of dominant components in the channel.
