Abstract

Spread-time code division multiple access (ST-CDMA) is an alternative CDMA scheme to spread spectrum (SS). The ST-CDMA is proposed for bandlimited multiple access channels, which can be considered the time-frequency dual of SS-CDMA. We propose a new ST-CDMA system based on the orthogonal complete complementary (CC) code. The performance of the proposed system is investigated and the simulation is done to compare with the conventional ST-CDMA system using PN codes. The results show the CC code-based ST-CDMA performs better than the existing system, which can be an additional choice for future multiple access communications systems.
