Abstract
In this Paper, we discuss reducing the number of orthogonal code in Multi-Code CDMA (MC-CDMA) system. MC-CDMA system is highlighted for multi-media communication services, but conventional MC-CDMA(CMC-CDMA) system are needed many more orthogonal codes compared to traditional direct sequence CDMA(DS-CDMA) systems. in this paper, we propose the system which can reduce the number of orthogonal codes using sub-orthogonal code(SOC) technique. We certificate that the performance of the proposed system shows the almost same result under gaussian noise environment as compared to CMC-CDMA system through Monte-Curio computer simulation method.
