Model-Driven Deep Learning Scheme for Adaptive Transmission in MIMO-SCFDE System
IEEE Access, 2020 Adaptive transmission (AT) is considered as one of the critical technologies to enhance the effectiveness of communication systems. In this article, we propose a model-driven deep learning (DL) scheme for AT in multiple-input multiple-output single ...

Hybrid Chirp Signal Design for Improved Long-Range (LoRa) Communications
Signals, 2022 Long-range (LoRa) communication has attracted much attention recently due to its utility for many Internet of Things applications. However, one of the key problems of LoRa technology is that it is vulnerable to noise/interference due to the use of only ...

Improved Schemes of Differential Spatial Modulation [PDF]
IEEE Access, 2021 Differential spatial modulation (DSM) is able to transmit additional data bits without increasing the number of radio-frequency chains and power consumption and also avoids pilot overhead. In this paper, we propose two new schemes of DSM to improve the original DSM.

Evaluations of elliptical modulation scheme
2004 IEEE Wireless Communications and Networking Conference (IEEE Cat. No.04TH8733), 2004 This work aimed to evaluate some modulation methods, which have been defined based on elliptical modulation scheme, namely are eccentricity shift keying (ESK), inclination angle shift keying (IASK) and elliptical phase shift keying (EPSK). In this paper, signal characteristics of these three modulation schemes and effect of eccentricity to the ...

Nonzero Staircase Modulation Scheme for Switching DC-DC Boost Converter
Journal of Control Science and Engineering, 2020 This paper presents a novel modulation scheme known as the nonzero staircase modulation scheme for switching DC-DC boost converters. This modulation scheme generates two distinct pulse trains/firing signals when a 50 Hz nonzero staircase modulating ...
