ScholarBank@NUS Repository. https://doi.org/10.1109/PGC.2010.5706012 | Abstract: | Transmission performance of free-space optical (FSO) communication is severely degraded by scintillation effect, which is a slow fading process. In this paper, we propose a dynamic decision threshold scheme to efficiently detect the bit stream. The decision threshold is varied in every sub-millisecond time slot. In addition, it is shown that coherent detection with 10dBm-local oscillator (LO) can make the BER performance better than 10-3 under different atmospheric turbulence scenarios from weak to strong. | Source Title: | 2010 Photonics Global Conference, PGC 2010 | URI: | http://scholarbank.nus.edu.sg/handle/10635/84077 | ISBN: | 9781424498826 | DOI: | 10.1109/PGC.2010.5706012 |
