Abstract :
Power control is an important requirement for code-division multiple access (CDMA) mobile wireless networks. Especially, it can effectively overcome the near-far problem. However, almost all existing power control algorithms assume that the time delay is known and fixed. While the time delay is often unknown or time varying under actual environments. This paper investigates power control of CDMA mobile wireless networks with unknown and time varying transmission delay. To compensate for the time-varying delay, a novel predictive power control algorithm is presented based on time delay estimation. Simulation results are given to demonstrate the effectiveness of the proposed algorithm.
