A semi-empirical method to compute the relative occurrence probabilities of minimum and nonminimum phase fades, occurring during selective fading, is presented. It is based on the assumption that the multipath fade depths at a single frequency are Rice distributed and that the total received power is constant. A Rice fade depth distribution can be parametrised with P_R, the relative mean power of the received Rayleigh distributed vector. The relative occurrence probabilities of minimum and nonminimum phase fades, depending on P_R, can then be computed for each radio path.
