The paper deals with statistical modelling of optimal space-time filter and jammer canceller, both based on delay taps for multipath mitigation. Distribution functions of phase and pseudorange errors and signal-to-noise ratio are presented. It was shown that optimal space-time filter doesn’t distort phase and pseudorange estimations in any signal and jamming environment.
