Two Statistical Cosite Signal-Prediction Models for Mobile Communication Systems

Two statistical cosite signal-prediction models are developed taking into account the effect of mutual coupling between antennas on a finite conductive earth. Both models predict the expected values of the desired and interfering signals, their standard deviations and correlation coefficients at the input terminals of a communication receiver, when such a receiver is in the near field of a transmitting antenna. Sufficient measured data are not available in the literature for various parameters of these models. The model must, therefore, be kept updated as measured data become available. Model 2 is in a form suitable for practical application. Further work is needed before Model 1 can be actually useful.
