Abstract

In this paper, the slotted ALOHA protocol in a mobile radio environment, in the presence of Ricean fading, two-fold antenna diversity and multiple reception capability, is considered. The capture probabilities and the average throughput are computed, and the issue of stability is addressed. It is shown that diversity can improve the system performance, although only to a certain extent. Some extensions are also considered: in particular, the use of a higher degree of diversity is investigated.
