In telecommunications, direct-sequence spread spectrum (DSSS) is a modulation technique. As with other spread spectrum technologies, the transmitted signal takes up more bandwidth than the information signal that modulates the carrier or broadcast frequency. The name spread spectrum comes from the fact that the carrier signals occur over the full bandwidth (spectrum) of a device s transmitting frequency.
