Measurement-based evaluation of interlink correlation for indoor multi-user MIMO Channels

Kolmonen, Veli-Matti; Haneda, Katsuyuki; Hult, Tommy LU ; Puotanen, Juho; Tufvesson, Fredrik LU and Vainikainen, Pertti (2010) In IEEE Antennas and Wireless Propagation Letters 9. p.311-314
Abstract (Swedish)
Abstract in Undetermined

The properties of the single-link multiple-input-multiple- output (MIMO) propagation channels have been analyzed in many studies based on extensive propagation measurements. In this letter, we extend the measurement-based analysis to dual-link MIMO propagation channels. Here, we examine interlink correlation by evaluating the correlation of eigenvectors obtained from multiple MIMO links. We also investigated how the physical propagation phenomena produced the interlink correlation. Results indicate that interlink correlation may exist. Sometimes it is found to be very high also for far separated receive units, depending on similarity of dominant propagation mechanisms between multiple MIMO links and... (More)
