摘要：
In this paper we show analytically how power allocated multi-user receivers in conjunction with power zones can be used to increase the capacity of CDMA cellular systems. The proposed scheme has two mutual benefits firstly, the increased sum-rate capacity of unequal power allocated multi user detection, and secondly we show that power zones can be used to significantly reduce intercell interference. Our results show that as the loading increases the benefits of power allocation and zoning increases as well. Our results show that using power allocation along with soft handover we can significantly increase the achievable cell loading over the conventional multi-user receivers.
