A single mode fibre pigtailed gradient index lens is used to minimise the modal effect of the optical link at different turbulence strengths. The proposed system is characterised in terms of the system transfer function, error vector magnitude (EVM), and optical launch power (OLP). Results demonstrate the robustness of the proposed scheme in terms of increased available passband bandwidth by 2 GHz and improving the transmission shape by reducing the system transfer function ripple by more than 5 dB. Successful transmission of the 4G-LTE signal is achieved over a MMF/SMF-FSO channel with a 1.5 dB power penalty under the higher turbulence level (i.e., Rytov variance of 0.1).}, keywords = {SYSTEM; PERFORMANCE; LONG-TERM EVOLUTION; LTE; Radio-over-fiber; radio-over-fibre; free space optics; multimode optical fibres}, year = {2016}, orcid-numbers = {Gerhátné Udvary, Eszter/0000-0003-3023-7810} } @inproceedings{MTMT:3170206, title = {Improvements on Broadband Signals in Radio Over Fiber Systems by Mode Filtering}, url = {https://m2.mtmt.hu/api/publication/3170206}, author = {Cseh, Tamás and Fekete, Gábor and Berceli, Tibor and Gerhátné Udvary, Eszter and Ali, Kabalan and Wosen, Kassa and Carlos, Viana and Anne-Laure, Billabert and Salim, Faci and Jean-Luc, Polleux and Catherine, Algani}, booktitle = {46th European Microwave Conference: Proceedings}, doi = {10.1109/EuMC.2016.7824502}, unique-id = {3170206}, year = {2016}, pages = {949-952}, orcid-numbers = {Gerhátné Udvary, Eszter/0000-0003-3023-7810} } @inproceedings{MTMT:3127157, title = {Integrated microstrip diplexers for Radio over Fiber}, url = {https://m2.mtmt.hu/api/publication/3127157}, author = {Nagy, A and Cseh, Tamás and Szalay, Zoltán Attila and Berceli, Tibor}, booktitle = {21st International Conference on Microwave, Radar and Wireless Communications (MIKON)}, doi = {10.1109/MIKON.2016.7492041}, unique-id = {3127157}, year = {2016} } @inproceedings{MTMT:3127149, title = {Experimental optimization of the hybrid RoMMF-FSO system using mode filtering techniques}, url = {https://m2.mtmt.hu/api/publication/3127149}, author = {Al-Musawi, HK and Cseh, Tamás and Bohata, J and Pesek, P and Ng, WP and Ghassemlooy, Z and Gerhátné Udvary, Eszter and Berceli, Tibor and Zvanovec, S}, booktitle = {2016 IEEE International Conference on Communications Workshops, ICC 2016}, doi = {10.1109/ICCW.2016.7503821}, unique-id = {3127149}, year = {2016}, pages = {405-410}, orcid-numbers = {Gerhátné Udvary, Eszter/0000-0003-3023-7810} } @article{MTMT:3003527, title = {Modeling and Simulation of Mode Filtered Radio over Multimode Fiber Links}, url = {https://m2.mtmt.hu/api/publication/3003527}, author = {Cseh, Tamás and Berceli, Tibor}, journal-iso = {INFOCOMM J}, journal = {INFOCOMMUNICATIONS JOURNAL}, volume = {7}, unique-id = {3003527}, issn = {2061-2079}, year = {2015}, eissn = {2061-2125}, pages = {20-27} } @inproceedings{MTMT:2918805, title = {The Effect of Laser Characteristics on Millimetre Wave Optical Generation Techniques}, url = {https://m2.mtmt.hu/api/publication/2918805}, author = {Fekete, Gábor and W.E., Kassa and Berceli, Tibor and S., Faci and Billabert, AL and C., Algani and Cseh, Tamás and Gerhátné Udvary, Eszter}, booktitle = {2015 17th International Conference on Transparent Optical Networks (ICTON)}, doi = {10.1109/ICTON.2015.7193348}, unique-id = {2918805}, keywords = {Heterodyne detection; photodiode; optical comb generation; Mach-Zehnder Modulator; optical phase locked loop; optical signal mixing; millimetre wave generation}, year = {2015}, orcid-numbers = {Gerhátné Udvary, Eszter/0000-0003-3023-7810} } @inproceedings{MTMT:2918785, title = {Experimental Demonstration of Transmitting LTE over FSO for In-Building POF Networks}, url = {https://m2.mtmt.hu/api/publication/2918785}, author = {Hassan, K Al-Musawi and Cseh, Tamás and Mojtaba, Mansour Abadi and Wai, Pang Ng and Zabih, Ghassemlooy and Gerhátné Udvary, Eszter and Berceli, Tibor}, booktitle = {2015 17th International Conference on Transparent Optical Networks (ICTON)}, doi = {10.1109/ICTON.2015.7193687}, unique-id = {2918785}, keywords = {TRANSMISSION; PERFORMANCE; FREE-SPACE; free space optics (FSO); polymer optical fibre; radio-over free space optics (RoFSO); radio-over-fibre (RoF); long-term evolution (LTE)}, year = {2015}, orcid-numbers = {Gerhátné Udvary, Eszter/0000-0003-3023-7810} }
