Abstract

In this paper we present a novel code family for SAC-OCDMA system. The new code technique is called Dynamic Cyclic Shift (DCS) code. Which more flexible in selection the code length with variable cross correlation. Furthermore, incase of increasing the number of users there is no need to increase the weight value. In addition the code construction is very simple and easy in compare with the former codes. The results show that the proposed code is effective to reduce the MAI, PIIN, while maintaining a good signal to noise ratio and bit error probability. The results obtained for the DCS code were compared with those obtained from different coding schemes Modified Quadratic Congruence (MQC) code and Random Diagonal (RD) code.
