摘要：

This paper present the results of a multiple-input multiple-output (MIMO) channel capacity measurement experiment conducted in an indoor line-of-sight (LOS) office environment. Channel responses were taken systematically with varying distance in a static indoor environment. Results showed measurements with high received signal-to-noise ratio (SNR) and a high level of correlation among the antenna elements. Further analysis of the results showed that MIMO systems can be efficient in the indoor LOS office environment, despite the high antenna correlation. Theoretical analysis reveals that when the SNR is sufficiently high, the loss in channel capacity due to high correlation is relatively low. Therefore it is shown that in the indoor LOS environment, MIMO systems can be achieve sufficiently high channel capacity because the MIMO channel is more robust to correlation when the SNR is high.
