A Generalised Wideband Space-Time MIMO Channel Simulator Based on the Geometrical Multi-Radii One-Ring Model

摘要

This paper extends the geometrical one-ring multi-input multi output (MIMO) channel model for a frequency flat fading process in a land mobile radio system with respect to frequency-selectivity. Our approach enables the design of efficient simulation models for space-time MIMO channels under isotropic scattering conditions for any numbers of transmit and receive antennas. A simulation study is performed into the space-time cross correlation to gain understanding of the modification of some relevant parameters. A conventional four transmit four receive 4×4 MIMO radio channel is analyzed.
