Abstract :
This paper investigates power control of code-division multiple access (CDMA) systems with random transmission time delay and uncertainty in communication channels. To deal with the random time delay and reduce the effects of uncertainty due to channel fading and interference, an adaptive power control algorithm is presented based on predictive control approach. Simulation results are given to demonstrate the effectiveness of the proposed algorithm.
