Abstract

Most Power Control Algorithms require that the link gain between an access port and a mobile terminal should be known. This means a centralized measurement mechanism to track the movement of mobile terminals should be employed which in turn will result into heavy signaling between access ports and mobile terminals. Hence the practicability of designing such systems is not trivial. In this study, focus was made on Distributed Power Control (DPC) algorithm which avoids the centralized power control schemes. Performance of DPC Algorithm and its convergence was done through simulation. The results show what may be expected when DPC power control is implemented in a practical system.
