Broadly tunable two-color lasing of Cr:LiCAF with on-surface and off-surface optical axis birefringent filters: performance comparison
(Applied Optics, 2022)
We studied the two-color lasing performance of a Cr:LiCAF laser using crystal quartz on-surface and off-surface optical axis birefringent filters (BRFs). Four different on-surface optical axis BRFs with thicknesses of 2 ...
A belt-integrated piezoelectric energy harvester for wearable electronic devices
(Ferroelectrics, 2021)
This paper reports a novel piezoelectric energy harvester incorporated on a waistbelt for power generation from waist movements. The device is composed of multiple piezoelectric disks in 3 D-printed encapsulations and ...
A sub-cm3 energy harvester for in-vivo biosensors
(Microelectronic Engineering, 2020)
The development of a kinetic energy harvester for in-vivo applications is reported. Consisting of an untethered magnetic platform encased by two stators, the device converts normal body movements into electrical power. A ...
Modified MU-STBC with round transmission for improving the date rate and reliability of future 6G and beyond wireless networks
(2023)
In this study, we present a novel multi-user scheme in which space-time block coding (STBC) is exploited for transmitting data in two rounds in a multiple-input multiple-output (MIMO) fashion while orthogonal frequency ...
Classifications and applications of physical layer security techniques for confidentiality: a comprehensive survey
(IEEE, 2019)
Physical layer security (PLS) has emerged as a new
concept and powerful alternative that can complement and may
even replace encryption-based approaches, which entail many
hurdles and practical problems for future ...
Improving the physical layer security of IoT-5G systems

Orthogonal frequency division multiplexing with subcarrier gap modulation
(IEEE 31st PIMRC'20 - Workshop on Waveform Design for Beyond 5G Communications, 2020)
A new modulation scheme called orthogonal frequency division multiplexing with subcarrier gap modulation (OFDM-SGM) is proposed. The proposed scheme embeds extra information bits by exploiting the gap between the active ...
OFDM-subcarrier power modulation with two dimensional signal constellations
(2019 Innovations in Intelligent Systems and Applications Conference (ASYU), 2019)
An original modulation technique has been recently proposed for wireless communication systems known as OFDM- SPM (OFDM with Subcarrier Power Modulation). This technique utilizes a characteristic of the subcarriers of the ...
An effective design for polar codes over multipath fading channels
(Springer, 2020-01)
Polar codes, recently adopted in 5G standard due to their excellent performance at a very low complexity compared to other competitive schemes in the literature, are deemed to be a strong candidate for the Internet of ...
