Adaptive Three Layer Hybrid Reconfigurable Intelligent Surface for 6G Wireless Communication: Trade-offs and Performance

no code implementations25 Sep 2023 Rashed Hasan Ratul, Muhammad Iqbal, Tabinda Ashraf, Jen-Yi Pan, Yi-Han Wang, Shao-Yu Lien

So, there might be a tradeoff between the additional energy consumption for the RIS technologies and the overall gain acquired by deploying this potential advancement.

Optoacoustic Signal-Based Underwater Node Localization Technique: Overcoming GPS Limitations without AUV Requirements

no code implementations10 Jun 2023 Maliha Tasnim, Rashed Hasan Ratul

In our model, the GPS signals are transmitted from the air to the underwater node through a mobile beacon that employs optoacoustic techniques to generate a short-term isotropic acoustic signal source.

Atmospheric Influence on the Path Loss at High Frequencies for Deployment of 5G Cellular Communication Networks

no code implementations2 Jun 2023 Rashed Hasan Ratul, S M Mehedi Zaman, Hasib Arman Chowdhury, Md. Zayed Hassan Sagor, Mohammad Tawhid Kawser, Mirza Muntasir Nishat

However, because 5G-NR operates at a high frequency and has significant propagation, atmospheric fluctuations like temperature, humidity, and rain rate might result in poorer signal reception, and higher path loss effects unlike the prior generation, which employed frequencies below 6 GHz.
