PERFORMANCE ANALYSIS OF MULTICARRIER DS CDMA SYSTEMS
|
Abstract:
In this paper, A multicarrier signaling technique is applied to a direct-sequence CDMA system. A data sequence multiplied by a spreading sequence modulates multiple carriers in transmitter, the receiver provides a correlator for each carrier, and the ouputs of the correlators are combined with a maximal-ratio combiner. This type of signaling has the desirable properties of a narrow band interference suppression effect. The system performance is evaluated in the presence of partial band interference, it is compared with that of a single-carrier DS CDMA system.
