DIGITAL BROADCASTING EMITTED RADIO SIGNAL POWER AMPLIFICATION METHOD AND DEVICE Russian patent published in 2018 - IPC H03F1/00 

FIELD: radio engineering and communications.

SUBSTANCE: claimed invention relates to the digital broadcasting emitted radio signal power amplification methods and devices. In the invention using the channels orthogonal frequency division, the digital signals OFDM conversion into the analog signal, its amplification to the required power and radiation, wherein in the process of the OFDM signal generation, performing its peak factor reduction in the certain sequence: first, implementing the reserve carriers method, and then applying the active constellation adaptive expansion algorithm for the OFDM signals peaks region conversion, and using the regenerative power supply unit, which accumulates energy in the pauses between the signals peaks.

EFFECT: technical result of the invention is a significant increase in the radio signals radiation efficiency on the transmitting side, increase in the transmitter energy efficiency and reliability, amplified signals dynamic range expansion without increase in the power supply unit power, nonlinear distortions reduction.
