1. Apparatus for providing real time adaptive power control in communication systems wherein a first station communicates an information bearing signal at a selected power level to a second station via a power limited repeater, said repeater having a power output which is functionally related to power input, along transmission paths which are subject to rapid onset signal attenuation, comprising quality monitor means for determining the short term quality of the information bearing signal as received by said second station from said repeater and for providing an indication which varies substantially in real time with said determined quality of said signal, and means at said first station for adjusting said selected power level in accordance with said real time indication so as to maintain said signal quality above a preselected threshold regardless of said rapid outset signal attenuation.
