Closed-loop power control in the reverse link of a DS/CDMA system is analys
ed. The transmitter/receiver based on IS-95 and the radio propagation chann
el under mobile communication environments are modelled and a new power con
trol algorithm is proposed. This algorithm utilises the burst error charact
eristics of the channel and can be directly applied to the current IS-95 sy
stem. The new power control algorithm. with respect to the SIR (signal to i
nterference ratio), increases;he service quality, and finally, enhances the
system capacity.
