• 論文の詳細を見る

• This paper aims at developing forward link power control methods for CDMA cellular systems. The purpose is to allocate available power to as many mobiles as possible. When a power allocation in the network is fixed, the power assigned to the cell where rare mobiles communicate is wasting, and moreover, is prohibitive if other cells fall short of transmitting power. In this case, re-allocation is necessary. Power control in this paper takes the form of allocating pilot and traffic power according to the different needs from each cell. Especially, the pilot power control method tends to balance nonuniformly imposed load through the network, and hence helps the network resources be utilized equally. With the proposed pilot control method, the number of simultaneously comunicating mobiles increases by 10-25% over the reference methods.
