Abstract :
This paper presents an orthogonal MC (multi-carrier) DS/CDMA system. In the system the data bits are transmitted in parallel with L branches where they are spread and modulated by orthogonal carriers. The performance of the system is studied in a slowly Nakagami fading frequency nonselective channel. The modulation schemes on each branch is the coherent FSK. For the system the performance is found to improve as the number of carriers increase.
