Performance of OCDMA system using OFDM technique based on flexible cross correlation code
This paper analyzes the performance of the OS-CDMA system using OFDM technique to enhance the channel data rate, to save power and increase the number of user of OSCDMA systems. This system compared with previous hybrid subcarrier multiplexing/optical spectrum code division multiple-access (SCM/OSCDMA) system. The average received SNR with the nonlinearity of subcarriers is derived. The theoretical results have been evaluated based on BER and number of users as well as amount of power saved. The proposed system gave better performance and save around -6 dBm of the power as well as increase the number of users twice compare to SCM/OSCDMA system. In addition it is robust against interference and much more spectrally efficient than SCM/OSCDMA system. The system was designed based on Flexible Cross Correlation (FCC) code.
