Abstract
A gain control circuit in a wireless distribution system (WDS) is provided. The gain control circuit generates a combined digital communications signal based on a number of received radio frequency (RF) communications signals. The combined digital communications signal has a digital amplitude(s) representing a summed analog power level(s) of the RF communications signals in a predefined number of binary bits. When the summed analog power level(s) exceeds a maximum analog power level represented by the digital amplitude(s) in the predefined number of binary bits, the gain control circuit determines a selected RF communications signal(s) causing the summed analog power level to exceed the maximum analog power level and attenuates the selected RF communications signal(s) to reduce the summed analog power level to below the maximum analog power level. As such, it is possible to achieve a calculated balance between performance, complexity, and cost in the gain control circuit.
