unipolar pulse
1.Abstract: Analyzes the performance of unipolar OCDMA system using optical orthogonal code (OOC) considering the dispersion and nonlinearity effect of the transmission medium.Theoretical analysis demonstrates that dispersion and nonlinearity effect deteriorate the system performance.The performance of OCDMA system assuming dispersion-shifted fiber as transmission medium is very close to the case neglecting the dispersion and nonlinearity effect.Assuming RZ initial pulse and optical hard limiter are also possible solutions.
