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