Abstract

We describe the real/imaginary and in-phase/quadrature covariance-matrix representations of the uncertainty in complex vectors supported by the StatistiCALTM software package, and transformations between these representations and the magnitude/phase uncertainty representation. We illustrate how the in-phase/quadrature representation combines some of the best aspects of the conventional real/imaginary and magnitude/phase representations.
