Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

ABSTRACT: New constructions of 3-dimensional optical orthogonal codes are presented. In each case the codes have ideal autocorrelation a = 0, and cross correlation of c = 1. All codes produced are demonstrated to be optimal. The constructions utilize a particular automorphism (a Singer cycle) of PG(k; q), the finite projective geometry of dimension k over the field of order q, or its affine analogue in AG(k; q).
