Paper Abstract

Multi-carrier technologies are emerging as a considerable force in the wireless world. OFDM charges ahead, with MC-CDMA close behind. However, as this tutorial demonstrates, multi- carrier technologies are not limited to OFDM and MC-CDMA. By application of Carrier Interferometry (CI) principles, we create CI/TDMA and CI/DS-CDMA, multi-carrier implementations of existing TDMA and DS-CDMA technologies. These implementations enable significant improvements in both performance and network capacity. Specifically, we double the network capacity of existing TDMA and DS-CDMA system and simultaneously outperform their traditional implementations. Of course, the benefits of Carrier Interferometry are not limited to TDMA and DS-CDMA: It also significantly improves the existing MC-CDMA and OFDM multi-carrier systems. What emerges is a very powerful technology that creates a common multi-carrier architecture for DS-CDMA, TDMA, OFDM, and MC- CDMA, bridging the hardware gap between the world's most promising technology, all the while enhancing network capacity and probability of error performance.
