Abstract :
This paper presents the effects of an algorithm for controlling the base station´s received target signal-to-interference ratio (SIR) according to the quality of the received frames on the capacity enhancement. It is proved that the algorithm presented has a smaller mean of the actual SIR received at the antenna than the existing method which applies the fixed target SIR needed for the worst case to all the users at every time instant. It is also shown that the capacity of the system can be further increased by optimizing the system parameters in the algorithm
