摘要: In power controlled CDMA systems, the number of users that each cell can support is limited by total interference received at base station and will vary with time. When a system congested, admitting new call only make link quality worse for ongoing calls may result in dropping. Thus, needs admission policy requests to maintain acceptable connections existing users. We use weighted combination blocking dropping probabilities as performance measure. study transmitted based control (TPCAC) scheme protects (RPCAC) blocks when exceeds threshold. The proposed schemes are evaluated simulation one dimensional RPCAC found offer significant improvements.
