Abstract :
Several coding alternatives for the implementation of OCDMA have been analyzed so far to improve the performance of the system. In this paper, integer lattice design based optical orthogonal code (OOC) has been discussed and analyzed for spectral amplitude coding schemes, applicable to both synchronous as well asynchronous incoherent OCDMA. Simplicity in code construction and flexibility in cross correlation control make this code a compelling candidate for future OCDMA applications. Signal to noise ratio (SNR) and bit error rate (BER) as a function of the number of users, code weight and userpsilas effective optical power have been analyzed for this code family. Further various parameters related to improvement of performance of BER have also been discussed in this paper.
