METHOD FOR COMPENSATING SIGNAL DISTORTION IN EMITTING PAYLOAD Russian patent published in 2012 - IPC H03F1/32 

FIELD: physics, communications.

SUBSTANCE: invention relates to a method of compensating signal distortion in an emitting payload. The method for compensating signal distortion in an emitting payload (GP) involves steps for determining a compensation transfer function (H_c(ω)) and introducing it into the aggregate response of the payload, the method being characterised by: choosing an initial tentative compensation transfer function ([H_c(ω)]_n) and introducing it into the aggregate response of the payload (GP); acquiring an output signal (Y(ω),y(t)) of the emitting payload; based on the acquired output signal and on a reference signal (X_ideal(ω)_; x_ideal(t)), corresponding to an expected undistorted output signal, performing an estimation of a residual distortion transfer function ([H_d(ω))]n) of the emitting payload; and based on the estimation of the residual distortion transfer function, computing an updated tentative compensation transfer function ([H_c(ω)]n+1) and introducing it into the aggregate response of the payload.

EFFECT: method of compensating signal distortion in an emitting payload without the need for obtaining the input signal of the payload.
