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

open access: yesEURASIP 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

A Cross-layer Perspective on Energy Harvesting Aided Green Communications over Fading Channels

open access: yes, 2013
We consider the power allocation of the physical layer and the buffer delay of the upper application layer in energy harvesting green networks. The total power required for reliable transmission includes the transmission power and the circuit power.

A Cycle-Based Formulation and Valid Inequalities for DC Power Transmission Problems with Switching

open access: yes, 2015
It is well-known that optimizing network topology by switching on and off transmission lines improves the efficiency of power delivery in electrical networks. In fact, the USA Energy Policy Act of 2005 (Section 1223) states that the U.S.
