In Optical CDMA (OCDMA) system MAI is recognized as most dominant source of noise. The authors have analyzed Optical Hard-Limiter (OHL) which is fixed threshold limiter at receiver to reduce MAI of the system. Also they have analyzed Two (OHL) for further reduction of MAI. But fixed thresholding becomes the limitation for random incoming signals so they have proposed dynamic thresholding with the help of Variable Optical Attenuator (VOA) before optical-electrical conversion at receiver to handle random incoming bits and reduce MAI. Hence, in this paper, they proposed a technique using Optical Normalizer (in Non Uniform Mode) for dynamic thresholding.
