System and method for amplifying a signal

摘要

An amplification system, connected to a modem delivering a signal to be amplified, includes at least one amplification device, at least one first determination device for determination of a first difference and at least one second determination device for determination of a variable gain. Moreover, the system is characterized in that the second determination device is capable of the determination of said variable gain on the basis of said signal to be amplified, said amplified signal and said first difference.

1. An amplification system, connected to a modem delivering a signal to be amplified, comprising:
at least one amplification device in which an amplification gain is variable, at least one first determination device for determination of a first difference between an amplified signal and said signal to be amplified, at least one second determination device for determination of said variable gain, wherein said second determination device is capable of the determination of said variable gain on the basis of said signal to be amplified, said amplified signal and said first difference; said second device having: at least one third determination device for determination of a model, comprising a delay and a gain, of a perturbation of the first difference by the amplification device by means of a correlation between said signal to be amplified and said amplified signal, at least one fourth determination device for determination of perturbations of the first difference that are caused by said amplification device, on the basis of said model and said signal to be amplified, at least one fifth determination device for determination of a second difference between said first difference and said perturbations, and a controller that is capable of determining said variable gain on the basis of said second difference.
