5.9.2 Adaptive Non-Linear Precorrection
The Non Linear Adaptive Filter provides the ARK6-T2 with an effective adaptive non linear
compensation.
The developed system is responsible for pre-emptively compensating the signal in order to make
unimportant the contribution of the intermodulation products due to the power amplifiers.
The signal passes through the power amplifiers and re-enters the system as to determine the distortion
and the compensating adaptive filter.
In order to enable the adaptive non linear precorrection, click on the ON/OFF button.
