Abstract :
Soft handover has two opposing effects on UMTS downlink systems, and there is a trade-off between them. The optimum size of the soft handover zone, is analysed in a power-controlled UMTS downlink system. The sensitivity of this optimum size to different system parameters, such as downlink orthogonal factor, path loss exponent, shadowing fading variable, is also analysed
