The measurement and characterisation of multiple-input multiple-output (MIMO) channels has gained increasing attention over recent years. Previous analysis of MIMO measurements has generally focussed on the evaluation of the capacity of such systems in differing locations and configurations. In this paper we present measurements made in an indoor environment at 5.2GHz, specifically to investigate temporal channel variation. Line-of-sight and non-line-of-sight situations are compared by means of

The conclusions are extended to encompass the rate of variation in performance of MIMO channels under different environmental conditions. 0-7803-7005-8/01/$10.00 0 2001 IEEE
