Adaptive WCDMA (P6)

Power control 6.1 ALGORITHMS In Chapter 8, we will show that the Code Division Multiple Access (CDMA) network capacity depends significantly on the so-called near–far effect. From the very beginning, theory and practice of CDMA were aware of this fact. All practical systems use Power control (PC) to reduce this effect. PC is more efficient in the system optimized for speech, such as IS-95. In a multimedia network such as Universal Mobile Telecommunication System (UMTS) in which different signals levels are used for different data rates, additional solutions like multiuser detectors are used. In IS-95, every mobile station attempts to adjust its...
