Performance of power control method for CDMA radio communications system
Chang Li, Sirikiat Lek Ariyavisitakul · Electronics Letters · 1991
Power control is used to solve the ‘near-far’ problem which arises in a spread spectrum system using direct sequence code-division multiple access (CDMA). A method to estimate the signal-to-interfercnce ratio to be used for power control is proposed and the difference in the signal-to-interference ratio between the set power control threshold and the average value actually received at the antenna over a fading multipath channel is presented.
