Abstract

In the bipolar OCDMA system

bipolar codes with better correlation properties are used in the conventional unipolar OCDMA channels in light of the unipolar-bipolar code transformation.A bipolar complete complementary sequence-based OCDMA system coding/decoding method and system model are proposed.The simulation results show that it has much better system properties than the Gold sequence-based OCDMA system and that using complete complementary sequences as the address codes

the MAI in the OCDMA system can be effectively reduced and the communication quality improved.
