Abstract: Based on the construction theory of optical orthogonal hopping codes, constructed the two dimensions MPC/OOC combination codes for the wireless-OCDMA system with the modified prime code as time spreading codes and the optical orthogonal codes as frequency hopping codes. This coding scheme has large code's capacity compared with the two dimensional codes in existence. By grouping, the MPC/OOC code has good performance in auto-correlation and cross-correlation with still quite large codes capacity. Designed the tunable FBG encoder and decoder to the construction example.
