Abstract :
In the framework of an UTRA-FDD system, simulated annealing is used to optimise the values of powers assigned to common pilot channel (CPICH) signals in order to force mobiles to transmit to the best option cell. Results show the existence of optimal configurations that decrease the cells load. Consequently, capacity can be increased
