Efficient power control reduces the interference in the whole network (increases capacity) and at the same time reduces the transmission power (increases battery lifetime of the mobile). Power control is the most important element in DS-CDMA, in particular on the uplink because many users access and use the same frequency and bandwidth at the same time, there is interference between the users. In the given seminar, As spreading and modulation have been explained, the following basic aspects of Power Control in Direct Sequence Code Division Multiple Access (DS-CDMA) are discussed below: Open-loop power control, Inner-loop power control, Inner-loop (slow) power control, Uplink power control, Downlink power control, a possible algorithm for initial power calculations.
