摘要: A method is disclosed that may include separating modes in a plurality of coherent time-domain signals to form separated modes, generating frequency coherence information for each the and combining combined information. An apparatus system processor storage device can be encoded with computer-readable instructions, wherein instructions when read executed by activities such as signals, recombining domain.
