Performance of multicarrier DS CDMA systems
S. Kondo,B. Milstein +1 more
TL;DR: This paper applies a multicarrier signaling technique to a direct-sequence CDMA system, where a data sequence multiplied by a spreading sequence modulates multiple carriers, rather than a single carrier.

Performance of orthogonal multi-carrier CDMA in a multipath fading channel
Essam Sourour,M. Nakagawa +1 more
TL;DR: It is shown that the DS-CDMA multi-carrier system over-performs the RAKE receiver when the system parameters are selected properly and the spread spectrum processing gain is increased, the effect of multipath interference is removed, and frequency/time diversity is achieved.
