Outer loop power control in a wideband CDMA system
1999 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

The third generation mobile communication systems are based on Code Division Multiple Access (CDMA) technology. The Wideband CDMA technology is the European standard and will be a world standard for third generation cellular systems. One of the main features in a Wideband CDMA system is power control. The power control is divided into two parts: fast power control and outer loop power control. In this thesis an algorithm for the outer loop power control has been studied and evaluated by simulations in a Matlab simulator called CURT (CDMA UMTS Radio Network Simulator). Different parameter settings for this algorithm has been used and evaluated. Simulations have shown that a slow algorithm tracks FER target better and has a lower standard deviation than a fast algorithm, whereas with a fast algorithm a more effective regulation is obtained during too good quality conditions. Furthermore a theoretical value for the reverse link capacity has been derived and compared to a simulated value. Simulations have shown a capacity of 130 Erlangs in comparison to a theoretical value of 188 Erlangs.
