What does a correlation matrix show?
A correlation matrix is simply a table which displays the correlation coefficients for different variables. The matrix depicts the correlation between all the possible pairs of values in a table. It is a powerful tool to summarize a large dataset and to identify and visualize patterns in the given data.
What is correlated channel?
Highly spatially correlated channels are characterized by frequency flat eigenbeams, allowing to reduce the feedback overhead by reporting only a wideband PMI (a single PMI over the entire system bandwidth). From: Mimo Wireless Networks (Second Edition), 2013.
What is correlation in MIMO?
The correlation coefficient (ρ) is an important metric for the evaluation of multiple-input–multiple-output (MIMO) antenna systems because it describes the relationship between the channels in a particular propagation environment. Highly correlated channels will degrade the MIMO system performance.
What is correlation in wireless communication?
In wireless communication, spatial correlation is the correlation between a signal's spatial direction and the average received signal gain. Theoretically, the performance of wireless communication systems can be improved by having multiple antennas at the transmitter and the receiver.
