Performance Estimation of the Forward Link in a Macrocell/Microcell Hierarchical Cellular Systems Using Code Division Multiple Access

摘要

In order to serve traffic hot spots, the hierar- chical cellular systems or the hybrid TDMA/CDMA have been proposed, recently. In order to depress the multi-user interference and increase capacity, the forward link power control strategy is adopted in the macrocell/microcell hierarchical cellular system using code division multiple access (CDMA). Its effects are es- timated in this paper. Especially, the impact of τ-th distance power control laws on the forward link outage probability and capacity plane for the hierarchical cellular system are investi- gated.
