SPREAD SPECTRUM MODULATION TECHNIQUES -spread spectrum - those modulation methods that are producing a signal whose spectrum is more wider than of the data signal, the occupied frequency band being independent by the signal of data band. -The signals with spread spectrum of direct sequence type BPSK (BPSK-DS-SS) -The signals with spread spectrum of direct sequence type QPSK – DS–SS - Frequency hopping spread spectrum signals (FH-SS)

In 揚(yáng)erformance of multi-carrier DS CDMA Systems?we apply a multi-carrier 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. The receiver provides a correlator for each carrier, and the outputs of the correlators are combined with a maximal-ratio combiner. This type of signaling has the desirable properties of exhibiting a narrowband interference suppression effect, along with robustness to fading, without requiring the use of either an explicit RAKE structure or an interference suppression filter.
