Transmission with SSB, as compared to conventional AM transmission, results in:

Single-Sideband (SSB) provides a massive efficiency advantage over conventional Amplitude Modulation (AM). In a standard AM signal, the continuous carrier consumes roughly two-thirds of the transmit power, and the two sidebands share the rest. By suppressing the carrier and one sideband, an SSB transmitter can concentrate all its available peak envelope power into a single information-carrying sideband, yielding an effective 6 dB (four times) power gain at the transmitter. At the receiver end, because an SSB signal occupies only half the bandwidth of an AM signal (e.g., 3 kHz instead of 6 kHz), the receiver's filters can be narrowed. This halved bandwidth lets in 50% less background noise, which improves the signal-to-noise ratio by another 3 dB. Combined, this gives a 9 dB total system advantage over conventional AM.
