Performance analysis of optical CDMA based on radio over fiber (RoF) technique
2016 3rd International Conference on Electronic Design (ICED), 2016This paper presents an improvement design of an Optical Code Division Multiple Access for Radio over Fiber (OCDMA-RoF) system. This improved system is divided into two main subsystems, Central Stations (CS) and Base Station (BS). Implement OCDMA code into RoF system promised a secure, cost-effective, and high-capacity mobile and multimedia wireless ...

Power Fading Effects in Millimeter-Wave Radio Over Fiber (RoF) Link
2015The use of fiber-based wireless system has offered a reliable and cost effective communication system. Such system greatly provides superior possible bandwidths for both fiber and free-space applications. For that reason, radio over fiber (RoF) technology is the best preference to deal with the improved capacity and mobility mainly at higher frequency.

Study on performance of Digitized Radio over Fiber (RoF) system using EDFA and Coherent receiver
The 2013 RIVF International Conference on Computing & Communication Technologies - Research, Innovation, and Vision for Future (RIVF), 2013In this paper, a calculating model of Digitized Radio over Fiber (RoF) system using EDFA amplifier and Coherent receiver is proposed. We then investigate Signal-to-Noise Ratio (SNR) in different parts of the system and establish SNRtotal equation at the output of RF signal recovery in three cases: Direct Detection, Coherent Detection and Combined EDFA ...

Survivability models for radio-over-fiber passive optical networks (RoF-PON)/PON
2011 seventh International Computer Engineering Conference (ICENCO'2011), 2011In this paper, we will propose some models for PON/RoF-PON combines a number of ideas used before in the research papers, the ITU-U recommendations and also a number of novel models. We compare between those proposed models by using the Expected Survivability Function; a simple and intelligent tool to evaluate network survivability.

NRZ and RZ analysis for optical CDMA based on radio over fiber (RoF) technique
2016 3rd International Conference on Electronic Design (ICED), 2016In this paper, we will focus on the modulation format used to produce the optical pulses, which are return to zero (RZ), and non-return to zero (NRZ). Bit error rate (BER) performance is assessed for OCDMA-RoF system. OCDMA-RoF system is viewed as a promising method for improving spectral efficiency and in the meantime diminish hardware equipment.
