Rain fade margin of terrestrial line-of-sight (LOS) links for 5G networks in Peninsular Malaysia
International Journal of Microwave and Wireless Technologies, 2021AbstractAdvanced telecommunication systems are moving toward a high data transfer rate and wider bandwidth. The 5G communication network has recently been implemented for such aims. However, 5G networks operating with high operating frequency (typically above 20 GHz) could lead to impairments because of the atmospheric phenomena mainly precipitation ...

Voice Delivery using The Visible Light Communication (VLC) Prototype on Line of Sight (LOS) Channels
2020 6th International Conference on Science in Information Technology (ICSITech), 2020Visible Light Communication (VLC) is the one of technologies used for 6th generation of telecommunications (6G), because it has a wide frequency spectrum, higher speed and safety. We have conducted an experiment using a prototype to transmit sound. Measurements were made by changing the receiving distance from 30 cm up to 300 cm in increments of 30 cm.

MIMO Channel Capacity in an Indoor Line-Of-Sight (LOS) Environment
IEICE Transactions on Communications, 2005The effect of antenna correlation on the Multiple-Input Multiple-Output (MIMO) channel capacity in the real propagation environment is a topic of interest. In this paper, we present the results of a measurement campaign conducted in an indoor Line-Of-Sight (LOS) office environment.

Sliding mode control based line-of-sight (LOS) stabilization of electro-optical sighting system
2016 IEEE 1st International Conference on Power Electronics, Intelligent Control and Energy Systems (ICPEICES), 2016Electro-optical sighting systems are used for surveillance, target acquisition and tracking. The stabilization of the line of sight (LOS) against vehicle-induced disturbances is an essential feature of the electro-optical gimbaled sighting systems, mounted on mobile platforms.

2018 IEEE/MTT-S International Microwave Symposium - IMS, 2018
This submission describes phased-array antenna (PAA) development efforts in mobile communications and sensor applications at Ku-band and higher. The application of heterogeneous integration to a phased-array beyond the integrated circuitry and electronics allows a significant reduction of piece-parts and the number of suppliers as well as improving ...
