摘要
In case of providing high data-rate service, the capacity analysis of CDMA forward link is required to allocate optimally high data-rate users. To solve this problem, we first analyze the capacity of CDMA forward link based on optimal power control. In 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 interference. Considering the location dependent factor, we propose coordinated allocation scheme, which can be used to allocate high data-rate users in sectorized cells. As a result, we show the capacity impact of high data-rate users according to location variation. It is also shown that the outage probability can be decreased, when coordinated allocation scheme is applied.
