If the phase of the theoretical mean of a complex-valued random variable is estimated by the sample mean of observed phases, there is a theoretical bias which results from the fact that phases are only measured on an interval of length 2pi, so that, for example, -pi and pi may represent the same phase. Thus if a true phase or direction is say, near pi, then the observed phases may instead be near -pi. In this paper, a least squares estimator of phase is proposed which accounts for this ";phase… CONTINUE READING
