DEVICE AND METHOD FOR ADAPTIVE LINEARIZATION OF ANALOG RADIO PATH THROUGH DUAL-DIGITAL CORRECTOR Russian patent published in 2018 - IPC H03F1/32 H04B7/05 

FIELD: means of communication.

SUBSTANCE: invention relates to the field of signal processing systems in communications. Adaptive linearization device of the analog radio path contains a two-block digital equalizer, a digital-to-analog converter (D/A converter), a frequency rise conversion path, power amplifier, down-conversion circuit, an analog-to-digital converter (ADC), an identification algorithm block, while a two-block digital equalizer contains a block of nonlinear inertial predistortion. Additionally, a second two-block digital equalizer, identical to the first one, and an adder, are introduced, and a block of inertial predistortion is introduced into the two-block digital correctors.

EFFECT: technical result is to reduce the number of optimization parameters of the adaptive algorithm without losing the quality of the digital linearization system.
