Development of wideband MIMO channel measurement system

A wideband wireless 4×4 multiple input multiple output (MIMO) channel measurement system is developed for characterizing MIMO channel.It is designed to work in four frequency bands from 2 GHz to 15GHz with 100MHz bandwidth.With this measurement system,initial measurements at 3. GHz for indoor propagation environment are presented.Typical indoor scenarios,such as line-of-sight (LOS) and non-line-of-sight (NLOS),are included.The influence of antenna spacing and pedestrian movement are also considered.The channel characteristic and parameters are extracted from the measurement campaign.The statistic parameters could be used to establish the discrete-time channel model and applied to the simulation and validation of wideband MIMO communication system.
