In a broadband DS-CDMA system, control of transmitter power is indispensable in order to solve the distance problem of mobile stations, in which the transmitter power of mobile stations is adaptively controlled so that the received power at the base station remains constant. In a DS-CDMA system, the paths can be separated and RAKE reception can be applied, which helps to reduce the transmitted power as well as the error in transmitter power control. This paper considers the case in which transmitter power control by feedback is applied to a DS-CDMA system, and analyzes the effects of control parameters such as the control time interval, the maximum amount of control, and the control step width, on the error of the transmitter power control, considering path and antenna diversity. © 2002 Wiley Periodicals, Inc.
