Abstract
In this letter we introduce a new performance measurement, the probability of false power control command (PFC), to evaluate the impact of measurement errors on the closed-loop power control in code division multiple access systems. We derive a closed-form expression for PFC. As compared to the variable-step-sized power control, we find that the fixed-step-sized CLPC scheme, thanks to its non-linear operation in the up/down control scheme, is less sensitive to the measurement error.
