Performance analysis of power control schemes in CDMA communication system

In CDMA cellular communication system power control is one of the most efficient methods to manage the resources, where the main capacity-limiting factor is co-channel interference. In this paper several closed loop power control algorithms are analyzed considering loop delay to cope with rando...

In this paper several closed loop power control algorithms are analyzed considering loop delay to cope with random changes of the radio channel and interference. Adaptive algorithms are considered that utilize ideas from self-tuning control systems. The inherent loop delay associated with closed loop power control can be included in the design process.
