Research on alleviating nonlinear problem by data feature extraction and fusion based on DFT-spread

EURASIP Journal on Advances in Signal Processing, 2023
Coherent optical orthogonal frequency division multiplexing (CO-OFDM) system is susceptible to nonlinear effects because of its intrinsic high peak-to-average ratio (PAPR). In this paper, two methods based on discrete Fourier transform spread (DFT-S) are

Wireless power transmission technologies

Радіотехніка, 2022
The article consists of three parts. The analysis of existing technologies of wireless power transfer (WPT) is carried out in the first part. It is noted that one of the factors that determines the choice of one or another WPT technology is the distance over which the power is transmitted and the type of electromagnetic (EM) energy used. The essence of

Wireless power transmission

Russian Technological Journal, 2020
Electrical energy from power plants to industrial facilities and settlements is mostly transmitted by wire-connected air or underground lines covering vast territories. However, in some rare cases there is a need for wireless transmission of electrical power to objects located in hard-to-reach areas.
