Correlation Measures for MIMO Systems
Multiple input- multiple output (MIMO) systems have the potential to achieve very high capacities, under the condition that the channel gains for different transmitter/ receiver pairs are decorrelated. In this paper, we compare the channel gains in terms of their complex, envelope and power correlation, based on measurements of a MIMO system under strong and weak line-of-sight conditions in an indoor environment. We study how similar the different correlation measures are and how they correspond to the physical propagation environment. Moreover we show how they affect the channel capacity.
