SSB, or Single SideBand, is a type of modulation used in radio communications. Some common synonyms for SSB include "Single SideBand Amplitude Modulation" (SSB-AM), "Single SideBand Suppressed Carrier" (SSB-SC), and "Upper SideBand" (USB), which refers to the high-frequency component of the signal. Another term related to SSB is "Double SideBand" (DSB), which refers to a modulation scheme that includes both USB and Lower SideBand (LSB) components. Additionally, SSB is sometimes distinguished from other forms of modulation, such as Frequency Modulation (FM) or Amplitude Modulation (AM). Regardless of the terminology used, SSB remains a vital technology for long-range communication in many industries, including aviation, maritime, and emergency services.
