Partial time delay compensation technique for UMTS adaptive power control

A modified version of the time delay compensation (TDC) technique for universal mobile telecommunication system (UMTS) power control called partial TDC or PTDC is proposed. The new technique relaxes the need for information of the exact number of loop delays. Simulation results show that an adaptive power control algorithm using the PTDC technique can achieve better performance than that of standard UMTS power control in the presence of delays.
