Abstract
Power control in 3G WCDMA System is studied in this paper. The basic power control techniques 3GPP Power Control Algorithm 1, 2 and Adaptive Step Power Control Algorithms are studied. The algorithm is based on an adaptive modification of the transmitted power update step size. The Adaptive-Step Power Control Algorithm, which could be easily implemented, is an interesting variant of the one-bit command PC of WCDMA System. We will show some results of the ASPC Algorithm for a given numerical parameters set of the algorithm. The quicker convergence of the ASPC (with regard to the present version of power control in WCDMA) may give a capacity increase.
The power control techniques plays the prominent role in enhancing the system performance and capacity in the interference limited network.There are several techniques to control the power of the WCDMA system that can be deployed in the network. But in this thesis we consider only some of them to show how the power control techniques are the important part in the wireless communication system. Among them, Adaptive Step Power Control Technique will be the major concern of study and also study the two algorithm of 3GPP Power Control Algorithm.
