+function CT = GenerateFakeCT(nSen, nTimes)
+% --------------------------------------------------------------------------- %
+% Generate random complex matrix with cross-spectrum-timeseries-like structure
+% 
+% real and imag parts of complex timeseries for CT generation are drawn from
+% standard normal distribution.

+% FORMAT:
+%   CT = GenerateFakeCT(nSen, nTimes) 
+% INPUTS:
+%   nSen        - scalar; number of sensors
