Title (EN) SCRAMBLER OF WIRELESS DEVICE
(FR) BROUILLAGE D'UN DISPOSITIF SANS FIL
Abstract: front page image
(EN)A CPU controls a spectrum inverting/noninverting switch and a subcarrier generator to transform a voice signal to be transmitted. Transmission is repeated alternately in the states of inverted and noninverted spectrum. On a reception side, the reverse transformation of signals is carried out. This improves the degree of privacy.
(FR)L'invention concerne une unité centrale commandant un commutateur inverseur/non-inverseur de spectre et un générateur de sous-porteuse afin de transformer un signal téléphonique devant être transmis. La transmission est répétée de manière alternative dans les états du spectre inversé et non-inversé. A la réception, la transformation inverse des signaux est déclenchée. Ce procédé permet d'améliorer le degré de confidentialité.
