Výzkum modulačních formátů pro optické sítě nové generace

Abstract

Main point of desertation thesis is study of theoretical principles access method OCDMA and OFDMA, because next task is design of optical scheme, which is using this access method. Purpose is design topology with advanced modulation formats and its simulation in software program OptiSystem 14 64-bit from Canadian company Optiwave. Because of simulation it can be evaluated, which method is more effective, or less sensitive to interference. Goal of final part is analysis data.

First part of diploma thesis is part, which contain studying principles of access method, mathematical principles is described too.

The second part compose from designing of optical network topology using OCDMA and OFDMA. Designed topology are simulated in software program Optiwave OptiSystem 14 64-bit.

Third part count conclusion, which contain analysis of result. For better evaluation i used graph created in mathematical software Matlab. Grafical representation of result provides clearer view on result.
