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.

Single-sideband (SSB) generation was invented 30 as a refinement of radio modulation for the efficient use of spectral bandwidth and transmission power, and for the mitigation of dispersion ...

AM, or amplitude modulation, was the earliest way of sending voice over radio waves. That makes sense because it is easy to modulate a signal and easy to demodulate it, as well. A carbon microphone… ...

In an SSB situation, this relates to the lower and upper sideband (Proakis, 1989), respectively Hence, if we want to transmit the analog signal x (t ) using SSB modulation, equation (5.90) replaces ...

Dunn recalls the history of SSB within ham radio from the 1950s when most voice communication was done through amplitude modulation.

This year, we recognize John R. Carson for two major contributions to communications technology: the invention of single-sideband (SSB) modulation and his rule for estimating ...

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 ...
