Abstract :
The space-time multiple-input multiple-output (MIMO) technique is being developed as the potential solution for future high data rate wireless mobile communications. Channel modeling is very important for the design and analysis of the MIMO space-time systems it. The paper develops a stochastic double directional indoor MIMO channel model, and validates it with measurement data. The model addresses the issue of signal clustering encountered in an indoor channel. Directions of departure and of arrival of signal clusters are both considered. The model is verified by comparison with published measurement data. The model describes an indoor MIMO channel directly using a reference SISO cluster channel model. The model also provides a simple yet tractable framework for further investigation on MIMO techniques in a clustering indoor environment.
