Investigation of Upper-Bounds on BER of OCDMA Systems Using Time Spreading/Wavelength Hopping Codes

The upper-bounds on BER of OCDMA systems using the time spreading/wavelength hopping codes is investigated with or without using the optical hard limiter.The thorough investigation and analysis on the performances of the systems is performed by simulation and it gets some valuable results. Reducing hit probability between codes and using optical hard limiter can effectively improve the performances of the system.
