WebFigure 13. Spectrum-analyzer photo of a DSSS signal. Note the original signal (nonspread) would only occupy half of the central lobe. Frequency-Hopping Spread Spectrum (FHSS) The FHSS method does exactly what its name implies—it causes the carrier to hop from frequency to frequency over a wide band according to a sequence defined by the PRN. WebDSSS is a method for sending data in which sender and recipient system are both on the set wide frequency is 22 MHz.
