A Time-Variant MIMO Channel Model Directly Parametrised from Measurements
This paper presents the Random-Cluster Model (RCM), a stochastic time-variant, frequency-selective, propagation-based MIMO channel model that is directly parametrised from measurements. Using a fully automated algorithm, multipath clusters are identified from measurement data without user intervention. The cluster parameters are then used to define the propagation environment in the RCM. In thi...
متن کاملModeling the Time-variant Mimo Channel
This paper studies two different modeling strategies for capturing the time-variant behavior of multiple-input multiple-output wireless channels. The first method generates a multi-variate random description of the channel matrix based on the measured space-time covariance. The second method describes the physical variation of the multipath propagation components with time. Information theoreti...
متن کاملCluster Parameters for Time-variant Mimo Channel Models
The next challenge for MIMO radio channel models is to simulate the time-variant nature of the channel correctly. Cluster-based MIMO channel models are well suited for this problem, however they currently lack an accurate parameterization of the time-variant cluster parameters. In this paper we identify and track clusters from three different measurements conducted in an indoor, a sub-urban, an...
متن کاملMeasurement-Based Time-Variant MIMO Channel Modelling Using Clusters
We present the novel Random-Cluster Model (RCM), a time-variant frequency-selective MIMO channel model. The most significant feature of the RCM is that it is parametrised directly from channel measurements by an automatic procedure. Thus, the RCM is specific to the environment, although it retains all advantages of a stochastic model. In this way it closes the gap between channel measurements a...
متن کاملA Wideband MIMO Channel Model Derived From
In this paper, we present a reference model for a wideband multiple-input multiple-output (MIMO) channel based on the geometric elliptical scattering model. The model takes into account the exact relationship between the angle of departure (AOD) and the angle of arrival (AOA). Based on this relationship, the statistical properties of the reference model are studied. Analytical solutions are pre...
