Abstract:
1. A method for dynamically determining the power compression point of an amplifier in a distributed network under the control of a computer, the network having a first terminal including the amplifier, the first terminal being operatively coupled to a plurality of second terminals by a communication channel, said method comprising: generating bit error rate (BER) messages indicative of a measured BER for a signal transmitted at each of N power levels, where N is a positive integer, each of said BER messages including data indicative of a power level, among the N power levels, corresponding to the measured BER in the each of said BER messages, at the second terminals; and reducing the maximum allowed power of the amplifier when it is determined that the amplifier is approaching saturation responsive to the generated BER messages, wherein the signal is transmitted at the N power levels prior to the reducing the maximum allowed power of the amplifiers, wherein the maximum allowed power of the amplifier is reduced based on each of the BER messages generated for the signal transmitted at each of the N power levels.
