Patent ID: 7450539

Claim:
A communication system, comprising: a plurality of channel power regulators, each sensing a corresponding input signal in a plurality of input signals and reducing said input signal in response to an indication that a composite signal formed from said plurality of input signals exceeds a threshold value; further comprising: a threshold detector which detects when said composite signal exceeds said threshold value; and an error signal generator which responds to said composite signal exceeding said threshold value by generating an error signal, said power regulators applying said error signal to said input signals to limit said composite signal to said threshold value; wherein: said error signal generator generates a desired composite signal with a magnitude limited to said threshold value and in phase with said composite signal; said plurality of channel power regulators are coupled to a multi-carrier communication channel; and said plurality of channel power regulators provide an allocation factor, said allocation factor being applied to said error signal to provide an uncompensated error signal.
