Abstract
An apparatus for gain control in a communication system is disclosed. The apparatus includes means for receiving at least one aggregate communications signal, the at least one aggregate communications signal comprising a summation of distributed communications signals, means for detecting at least a sample of a signal level of the at least one aggregate communications signal, and means for attenuating the signal level of the at least one aggregate communications signal based on the signal level sample.
