Abstract

The cell capacity is determined for a direct-sequence code-division multiple-access (CDMA) communications system that employs power control of the transmitted signal in the presence of doubly selective fading. The influence of the power-control delay and the delay spectrum and Doppler spread of the channel on the cell capacity and the effectiveness of the power-control method is examined. The sensitivity of the performance of the power control to the chip rate of the direct-sequence waveform and the number of taps in the RAKE receiver is also discussed. Both open-loop and closed-loop power control. Are considered
