You can use the Coherence transform to calculate coherence-related measures between two
channels or signals, which yield a channel pair. All these measures are based on signal representation
in the frequency domain as obtained by the FFT transform. For an appropriate interpretation
of the result, stationarity of the involved signals is assumed. The output of this
transform is an average over all available segments.
