| General note | ABSTRACT<br/>In this research the performance of degraded optical communication system due to<br/>chromatic dispersion is optimized. First an analog test signal is generated and<br/>converted into digital and modulated with 16 QAM by gray code mapping. Through<br/>Split step technique the signal is propagated in the optical fiber link. After 15 Km<br/>travel of signal through simulation the chromatic dispersion is noticed. To reduces<br/>this dispersion the signal is converted in electrical form at end of optical fiber link.<br/>Digital Signal Processing techniques (LMS and FFT algorithm, window) are applied<br/>on dispersed signal to reduces the Chromatic dispersion. Pulse shaping filter (raised<br/>cosine filter) is used which improves the shape of signal. Finally Bit Error Rate and<br/>Eye Diagram are compared before and after the induction of chromatic dispersion into<br/>test signal while travelling in to a fiber optic communication system. Entire work is<br/>performed in Matlab environment and Graphical user Interface is designed in MS<br/>visual studio.<br/>The CD is reduced electronically so it will save the requirement of hardware and<br/>change of optical fiber in comparison to another available method of reduction in<br/>chromatic dispersion which is Dispersion Compensation Fiber (DCF).<br/> |
