Capacity estimation of forward link in CDMA systems supporting high data-rate service

The capacity analysis of CDMA forward link is required to allocate high dat a-rate users. To solve this problem, we analyze the capacity of the CDMA fo rward link based on optimum power control. In a multi-cell environment, the intracell interference and intercell interference are derived. To show the capacity impact of high data-rate users. we introduce a location dependent factor. which is the ratio of intercell interference to intracell interfer ence. Considering the location dependent factor, we propose a coordinated a llocation scheme that can be used to allocate high data-rate users in secto rized cells, As a result, we show the capacity impact of high data-rate use rs according to location variations. The outage probability can be decrease d when the coordinated allocation scheme is applied.
