Abstract
A system and method for optimal adjustment of gain of a network amplifier, and for substantially reducing oscillation produced by a network amplifier. The network amplifier includes first and second antennas for the transmission of signals between a handset and a base station. The signals are amplified by first and second variable gain modules by an amplification factor as determined by a control circuit. The control circuit determines the optimal value of the amplification factors by analyzing the signals. In the event that an oscillation is detected, the control circuit adjusts the amplification factors in a manner that substantially reduces the oscillation.
