Analysis of received level characteristics with transmitter power control in W-CDMA system

Wideband DS-CDMA systems must offer transmitter power control in MSS to minimize each user's interference to the uplink communications paths of other users. In CDMA systems, received level error with adaptive transmitter power control (ATPC) can be improved easily by using RAKE reception because the multi-path components are separated and combined effectively. In this paper, we clarify the received level error taking into account the transmitter power control parameters such as control interval, control step width, etc, by RAKE reception using path diversity and antenna space diversity.
