An improved product construction is presented for rotational Steiner quadruple systems. Direct constructions are also provided for small orders. It is known that the existence of a rotational Steiner quadruple system of order v v þ 1 implies the existence of an optimal optical orthogonal code of length v v with weight four and index two. New infinite families of orders are also obtained for both rotational Steiner quadruple systems and optimal optical orthogonal codes.

“…T HE main factor of performance degradation in optical code-division multiple-access (CDMA) systems is the multi-access interference (MAI) [1]- [7]. In spectral amplitude-coding (SAC) systems [1]- [3], MAI is solely a function of the in-phase cross correlations among the address sequences (also known as signature sequences or spreading sequence or simply code sequences).…”

Abstract-A novel balanced detection scheme for multi-access interference cancellation in multimedia spectral-amplitude-coding optical code-division multiple-access system is proposed. The receiver is capable of handling both equal and unequal in-phase cross correlation of optical orthogonal codes. A novel class of constantlength variable-weight optical orthogonal codes able to support multimedia services with different quality-of-service requirements is proposed as well. The construction is based on the pairwise balanced designs, or more specifically, on an incidence structure defined on an integer sub-lattice.Index Terms-Integer lattices, multi-access interference (MAI), multimedia, optical code division multiple access (CDMA), optical orthogonal codes, pairwise balanced designs, spectral-amplitudecoding (SAC).
