Controlled-envelope single-sideband modulation
Appearance
CESSB (controlled envelope single-sideband) is a narrowband modulation method using a single-sideband, whose the peak envelope level is controlled so that the peak-to-average power ratio of CESSB is much reduced compared to standard SSB modulation and offers improved effective range over standard SSB modulation while simultaneously retaining backwards compatibility with standard SSB radios.
CESSB is being used experimentally by amateur radio operators.
