Orthogonal Frequency Division Multiplexing is a multicarrier modulation technique which segregates the accessible spectrum into subcarrier, among every subcarrier attaining a low rate data stream. A large number of research work has been developed till now to enhance the performance of the system. Specifically the downstream transmission is considered as the prominent topic among the researchers. For this, in traditional work, an OFDM-PON communication system using m-QAM mapped mechanism was developed but found to be less efficient with the perspective of data rate, subcarriers and channel...

Le multiplexage par répartition orthogonale de la fréquence est une technique de modulation multiporteuse qui sépare le spectre accessible en sous-porteuses, chaque sous-porteuse permettant d'obtenir un flux de données à faible débit. Ungrand nombre de travaux de recherche ont été développés jusqu'à présent pour améliorer les performances du système. En particulier, la transmission en aval est considérée comme le sujet le plus important par les chercheurs. Pour cela, dans les travaux traditionnels, un système de communication OFDM-PON utilisant un mécanisme mappé m-QAM a...

Orthogonal Frequency Division Multiplexing ist ein Mehrträgermodulationsverfahren, das das zugängliche Spektrum in Unterträger aufteilt, wobei jeder Unterträger einen Datenstrom mit niedriger Rate erhält. Bisher wurde einegroße Anzahl von Forschungsarbeiten entwickelt, um die Leistung des Systems zu verbessern. Insbesondere die Downstream-Übertragung wird als das herausragende Thema unter den Forschern betrachtet. Dazu wurde in traditionellen Arbeiten ein OFDM-PON-Kommunikationssystem mit m-QAM-Mapping-Mechanismus entwickelt, das sich jedoch im Hinblick auf Datenrate, Unterträger und...

This work is for a basic understanding about the synthesis process of ZnO structures like nanoparticles (NPs) and nanowires (NWs). ZnO NPs and NWs have been successfully prepared by using successive ionic layer adsorption and reaction (SILAR) methods under a normal environment. The optical properties of as-synthesized NPs and NWs are characterized by using different techniques like photoluminescence (PL) spectroscopy and UV-Visible (UV-Vis) spectroscopy. The structural and morphological properties of prepared morphologies of ZnO were investigated by Xray diffraction (XRD) and scanning...
