Design of new hybrid wavelength hopping/time spreading codes for optical CDMA by combining OCC and BIBD ZCC codes

A new family of two-dimensional optical hybrid code, which employs optical complementary codes and zero cross correlation codes, constructed by the balanced incomplete block design, as time spreading and wavelength hopping patterns, respectively, is proposed in this paper. The obtained codes have both off-peak autocorrelation and cross-correlation values respectively equal to zero and unity.
