In my reference paper related to wireless communication the covariance matrix is made from vector comprising of channel coefficients. And non zero eigen values of the covariance matrix are calculated. What does this signify with reference to wireless communication.

  • $\begingroup$ Please edit your question with a link to your "reference paper", unless it is behind a paywall, in which case please edit your question with an excerpt showing how the covariance matrix is constructed. $\endgroup$ – TimWescott Feb 18 at 5:35
