Journal ArticleDOI
Performance enhancement of outdoor visible-light communication system using selective combining receiver
It Ee Lee,Moh Lim Sim,F. Kung +2 more
TL;DR: An analytical daylight noise model based on a modified Blackbody radiation model is proposed to capture the effect of ambient-light noise and an in-depth study on the impact of daylight on the system performance is conducted.
Proceedings ArticleDOI
Performance analysis of free space optical links over turbulence and misalignment induced fading channels
TL;DR: This study reveals that lower outage probability can be achieved with larger receiver aperture due to the aperture averaging effect, and can be treated as the design benchmark for optimal planning and deployment of optical links.
Journal ArticleDOI
Effects of aperture averaging and beam width on a partially coherent Gaussian beam over free-space optical links with turbulence and pointing errors.
TL;DR: It is demonstrated that the maximum channel capacity is best achieved through the introduction of a larger receiver aperture and a beam-width optimization technique, and this parameter should be adjusted according to the varying atmospheric channel conditions.
Journal ArticleDOI
Joint optimization of a partially coherent Gaussian beam for free-space optical communication over turbulent channels with pointing errors.
TL;DR: Results show that near-ideal average capacity is best achieved through the introduction of a larger receiver aperture and the joint optimization technique.
Proceedings ArticleDOI
Practical implementation and performance study of a hard-switched hybrid FSO/RF link under controlled fog environment
It Ee Lee,Zabih Ghassemlooy,Wai Pang Ng,V. Gourdel,Mohammad-Ali Khalighi,Stanislav Zvanovec,Murat Uysal +6 more
TL;DR: The authors' measurement results reveal that the selection of a desirable threshold voltage is dependent upon the intended data rate and minimum achievable bit error rate, in order to enable effective switching between the FSO and RF links.
