Green communication systems via a wavefront multiplexing technique
Systems Engineering, Volume 28, Issue 1, Page 5-14, January 2025.Abstract A green communication scheme using an orthogonal wavefront (WF) multiplexing (Muxing) scheme spatially combined with orthogonal frequency‐division multiplexing (OFDM) techniques is proposed. It forms a spatial WF OFDM transceiver. The WF Muxing technique serves as the preprocessing and postprocessing method of the WF OFDM transceiver.

QROP: Quantum Learning‐Based Identification of Retinopathy of Prematurity
IET Quantum Communication, Volume 6, Issue 1, January/December 2025.This work aims to classify normal and ROP‐affected retinal images using a quantum neural network (QNN). The proposed system uses the HVDROPDB (2023) dataset fundus images of preterm infants. The proposed system achieves 97.06% accuracy with the HVDROPDB Neo dataset, 91.18% accuracy with the HVDROPDB RetCam dataset, and 85.29% accuracy when evaluated on
