RoF Networks : A comprehensive study
2008 3rd International Symposium on Wireless Pervasive Computing, 2008We present a comparative study of different Fiber-Wireless networks with regards to their applications, architecture, hardware complexity, development costs, offered services and allocated bandwidths. While spectral resources and high data-rates are incessantly requested, these radio over fiber (RoF) networks have been proposed to overcome limitation ...

An overview of integration of RoF with PON
2010 International Conference on Computer Application and System Modeling (ICCASM 2010), 2010With the emergence of high-bandwidth services such as IPTV, the access network system is putting pressure to increase the bandwidth for different services. This paper demonstrates the integration configuration of RoF and PON, which takes full advantage of huge bandwidth offered by fiber and mobile features presented by wireless scheme. It is an optimal

Multiclass Segmentation by Iterated ROF Thresholding
2013Variational models as the Mumford-Shah model and the active contour model have many applications in image segmentation. In this paper, we propose a new multiclass segmentation model by combining the Rudin-Osher-Fatemi model with an iterative thresholding procedure.

ROF-RVC based mobile CATV system
14th IEEE Proceedings on Personal, Indoor and Mobile Radio Communications, 2003. PIMRC 2003., 2004This paper reports about fundamental transmission performance for ROF-RVC based mobile CATV system. We have proposed the concept of multiple services transmission for RVC system, where several services signals are integrated on the same radio frequency band by exploiting the broadband transmission capability of ROF system, and thereby achieves simple ...

Optically reconfigurable fractal antennas for RoF systems
2012 35th International Conference on Telecommunications and Signal Processing (TSP), 2012This study presents the operating frequency reconfigurability for the Sierpinski gasket fractal antenna. This design may be a good candidate for RF over fiber (RoF) systems in which the built-in optical systems have already been included. Doped silicon with a suitable laser light is considered as a switching component.

Architectures for Joint Compensation of RoF and PA with Nonideal Feedback
2010 IEEE 71st Vehicular Technology Conference, 2010A high capacity wireless communication system requires careful design to minimize interference and distortion effects. This paper considers the adaptive predistortion of the nonlinear distortions induced by a Radio over Fiber (RoF) link and power amplifier (PA) connected in series. In particular, we study the architectures for the joint compensation of
