The implementation of conventional Multi-Code Code Division Multiple Access (MC-CDMA) system needs many orthogonal codes (OCs) compared to traditional Direct Sequence-CDMA (DS-CDMA) systems. To reduce the number of OCs in MC-CDMA for multi-media services, we propose a new scheme in which a sub-orthogonal code (SOC) technique is adopted. To clarify the validity of our proposed system, the computational simulations have performed.
