Abstract :
In this paper, we have shown that optical code division multiplexing (O-CDMA) systems at 10 Gb/s that can support at least 10 simultaneous users with BER<10-9 can be effectively designed for implementation in real networks. The carrier-hopping prime code is chosen to offer the optimum correlation values and maximum cardinality while providing a satisfactory bit error rate (BER). The encoder design can be advantageous of scalability allowed by increasing the code matrix size and the complementary decoder reduces cardinality limitations.
