Abstract

Abstract:

A downlink admission control (AC) algorithm is proposed in code division multiple access （CDMA）systems, that is based on multi-cell transmitted power raised estimation. The transmitted power raised in the adjacent base stations is taken into account as well as in the serving one when a new call is arrived. A method is derived to estimate the transmitted power in the adjacent base stations. Simulation results show that under non-homogeneous conditions, the proposed algorithm reduces the probability of wrong admission, accordingly the throughput is increased.

Key words: code division multiple access , admission control, power raised
