Abstract
Abstract A system and method for optimizing power control provides dynamic adjustment of a power-control threshold thereby allowing transmitter power to be reduced when signal quality is high. In a communication system having at least one mode for controlling the power of a transmitter in the communication system, the threshold level of the system is optimized by determining performance of the communication system based on a predetermined metric such as the system error rate, for example. Additionally, the power of the transmitter or transmitted signal in relation to the threshold of the communication system is determined. The threshold of the communication system is adjusted based on the performance of the communication system and the power of the transmitter in relation to the threshold.
