{(VO),IET}和相关的复值过程{X(t),te T},令X(t)= U(t)+ iV(t). {X(t)}的性质显然总是可以从二元过程的性质中得到。例如,{X(t)}的自协方差函数,定义为
{(VO), IET} and an associated complex-valued process {X (t), te T} by letting X (t)= U (t)+ iV (t). Properties of {X (t)} can clearly always be obtained from properties of the bivariate process. For example, the autocovariance function of {X (t)}, defined by
