Evaluación de escenarios de simulación de formatos de codificación binaria utilizado en comunicaciones ópticas.

Abstract

This work performs the evaluation of simulation scenarios of binary coding formats (NRZ and DB) used in optical communications. Currently, optical communications systems use binary encodings, among the most prominent are non-return to zero (NRZ), return to zero (RZ) and duobinary (DB). Chapter 1 describes the generalities of the complex component work, among the most prominent, the definition of the problems, justification and objectives. Chapter 2 briefly describes the theoretical foundations of the Hardware Description Language (VHDL) design methodology and the duobinary system used in optical communications. Chapter 3 designs the simulation scenarios of the non-return to zero (NRZ) and duobinary coding systems, and the evaluation is based on comparing the results obtained for the different proposed scenarios. Two tools were necessary for the implementation, MatLab / Simulink and VHDL. Finally, the conclusions and recommendations for future work are presented.
