Wavelength-Time Optical CDMA Scheme Adopting Commercial 2m×2m Arrayed Waveguide Gratings

摘要

One new code family with asymptotically optimal cardinality is proposed for high-speed OCDMA networks. This code family has short code lengths and can adopt commercial 2m ×2m arrayed waveguide gratings for coder implementation (m is positive integer). The performance analysis shows that the proposed codes have improved spectral efficiency as compared to wavelength/time codes generated from other coding schemes with asymptotically optimal cardinalities.
