Abstract
"Syncompex" is an acronym for "synchronized compressor and expander" and is a system designed to be used with HF single-sideband radio telephone equipment to improve its performance in the presence of interference and fading. It can be used either as an integrated part of a radio design or as a retrofit to existing equipments. The concept is functionally similar to Lincompex but is implemented with modern technology to reduce its cost and to allow its use in conjunction with commercial grade radios. Preliminary evaluation of this system over two HF skywave paths is described. Significant improvements in voice quality and intelligibility were observed during periods of low signal-to-noise ratio.
