CAPTURE PROBABILITIES IN RANDOM-ACCESS MOBILE COMMUNICATIONS IN THE PRESENCE OF RICIAN FADING

In this paper, the capture probabilities. C-n, defined as the probabil ity that any of the n contending packets are correctly received, are f ound with reference to a random-access mobile radio communications sys tem in the presence of fading, shadowing, and near-far effect, A Ricia n model for fading that is more general than the well-studied Rayleigh fading is considered, The capture probabilities are computed, and the ir dependence on the system parameters and, in particular, on the Rice factor, K, is investigated. As an example of application, a slotted A LOHA system is considered. and the performance of a simple control str ategy is studied, Also, some analytical results art given as to the va lue of C-x = lim(n-x) C-n, which is relevant to the study of the syste m stability.
