Background Radiation Cancellation for Free-Space Optical Communications with IM/DD
Tianyu Song, Pooi-Yuen Kam
Besides atmospheric turbulence and pointing errors which cause the signal intensity fluctuation, background radiation also impairs the free-space optical intensity-modulation / dir…
Efficient Symbol Detection for the FSO IM/DD System with Automatic and Adaptive Threshold Adjustment: The Multi-level PAM Case
Tianyu Song, Pooi-Yuen Kam
To detect M-ary pulse amplitude modulation signals reliably in an FSO communication system, the receiver requires accurate knowledge about the instantaneous channel attenuation on…
Robust Data Detection for the Photon-Counting Free-Space Optical System with Implicit CSI Acquisition and Background Radiation Compensation
Tianyu Song, Pooi-Yuen Kam
Since atmospheric turbulence and pointing errors cause signal intensity fluctuations and the background radiation surrounding the free-space optical (FSO) receiver contributes an u…
A Robust and Efficient Detection Algorithm for The Photon-Counting Free-Space Optical System
Tianyu Song, Pooi-Yuen Kam
We propose a Viterbi-type trellis-search algorithm to implement the FSO photon-counting sequence receiver proposed in [1] more efficiently and a selective-store strategy to overcom…
Efficient Direct Detection of M-PAM Sequences with Implicit CSI Acquisition for The FSO System
Tianyu Song, Pooi-Yuen Kam
Compared to on-off keying (OOK), M-ary pulse amplitude modulation (M-PAM, M>2) is more spectrally efficient. However, to detect M-PAM signals reliably, the requirement of accurate…
