The dispersion-induced phase noise (PN) in an OFDM RoF system at 60 GHz leads to not only subcarrier phase rotation (PRT) but also intercarrier interference (ICI) to severely degrade the transmission performance, when a commercial cost-effective DFB laser with the linewidth of several MHz is adopted. To mitigate both PRT and ICI, a post PN suppression algorithm is proposed, and it does not requ...

We study a central difference discretization of Rudin-Osher-Fetami model for image de-noising. We show that the discrete solution uk converges to the continuous solution u in L2 norm and a rate of convergence is given.

The Radio over Fiber (ROF) communication technology combines the technical blessings of each fiber communication and wireless Cellular communication to unravel the issues of information measure, flexibility and magnetic attraction interference. Future generation of cellular Communication system should be capable of serving prime quality and broadband services even in extremely dense urban area....

The cost of human operation is a bottleneck in the restoration of large quantities of archive films. Eliminating the vibration of a degraded image makes a difficulty in an automatic film restoration system. The vibration is usually caused by improper film transportation during the recording, copying or the digitization process. We have developed an automatic method for image stabilization consi...

prepare masters and doctoral theses. He actively participated rofessor Michel Abu Jamra was born on August 13, 1916. Durng the 10th Recycling Course of Hematology and Transfusion edicine of Hospital Israelita Albert Einstein held in conjuncion with the MD Anderson Cancer Center, we could not fail to ay tribute to the 100 years that would have been completed y this eminent professor. This homage...
