Photonic generation of ASK microwave signals with SSB format can significantly relieve the bandwidth restriction set by optoelectronic devices in high-speed microwave communication systems.
Compared with conventional single-sideband (SSB) modulation, the electrical SE is doubled without sacrificing the receiver sensitivity.
A recent video from [W2AEW] shows how this works and also how AM can be made more efficient by stripping the carrier and one sideband using SSB or single sideband modulation.
It uses SDR techniques and a combination of AM and FM to achieve polar modulation and generate SSB. He’s provided a fascinating in-depth technical explanation to help understand how it works.
Abstract Field tests are described which investigate the transmission of compatible-single-sideband signals from a typical high-power transmitter for high-frequency broadcasting and which compare ...
Dunn recalls the history of SSB within ham radio from the 1950s when most voice communication was done through amplitude modulation.

This paper will offer, in detail, a method utilizing single-sideband suppressed carrier (SSBSC) modulation of the stereophonic subcarrier in the FM multiplex baseband that is compatible with existing ...
Does FM single-sideband suppressed-carrier modulation outperform conventional double-sideband suppressed-carrier modulation? Many observers say the evidence in favor of FM SSBSC is anecdotal and that ...
