Abstract :
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-interference 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.
