WebDSSS and FHSS are the two techniques most in use today. Direct-Sequence Spread Spectrum (DSSS) With the DSSS technique, the PRN is applied directly to data entering the carrier modulator. The modulator, therefore, sees a much larger bit rate, which corresponds to the chip rate of the PRN sequence. WebSchool of Computing and Information University of Pittsburgh
