Using analytical approach, we investigate the impact of spatial diversity on the Erlang capacity of reverse link direct sequence code division multiple access (DS/CDMA) system. Several parameters which can affect the capacity are considered: transmit diversity order, spatial receive diversity order, the number of multipaths, fade distribution and arbitrary multipapth intensity profile, maximum transmit power, soft-handoff, and traffic distribution with call admission control scheme.
