Abstract :
Single-sideband high frequency communications systemhs have several advantages over AM, PM, and FM for long-range communications. These advantages include low harmonic and intermodulation distortion due to the behavior of the transmission medium, more efficient use of spectrum, and better power efficiency. Proposed precise frequency control would make it possible to employ single-sideband systems for a great many applications, including unlimited netting, that are currently outside the capabilities of conventional single sideband. It is anticipated that precise frequency-controlled single sideband can be employed to increase the reliability utility, and capacity of military and commercial hf radio communications.
