Background
As the demand for cellular wireless systems increases, there is a growing need for power control techniques that minimize inter-user interference and extend the battery life of mobile handsets. Without power control, the signal received by the base station from a nearby mobile handset will dominate the signal from a far-away handset, resulting in severe signal interference and power drainage. Conventionally, the transmission power of each mobile handset varies based on its distance to the base station: the closer to the base station, the less the transmission power.
