For any spread spectrum technology, the number of active users at a given data rate with acceptable level of BER and quality factor are highly dependent on type of sequence selected for spreading and de spreading. In this paper 3D temporal/ spectral / spatial codes based on optical orthogonal codes and different operators from algebra theory are considered at data rate up to 10 Gb/s per user with variable received power till - 36dBm for 3D OCDMA. The different models thus designed are compared in terms of eye diagram, signal strength, BER and quality factor. Performance of designed 3D OCDMA system is higher and is compared with the simulated results from other researchers available in terms of number of active users, BER and data rate.

Abstract


For any spread spectrum technology, the number of active users at a given data rate with acceptable level of BER and quality factor are highly dependent on type of sequence selected for spreading and de spreading. In this paper 3D temporal/ spectral / spatial codes based on optical orthogonal codes and different operators from algebra theory are considered at data rate up to 10 Gb/s per user with variable received power till - 36dBm for 3D OCDMA. The different models thus designed are compared in terms of eye diagram, signal strength, BER and quality factor. Performance of designed 3D OCDMA system is higher and is compared with the simulated results from other researchers available in terms of number of active users, BER and data rate.
