Abstract
(EN)
A transmitting apparatus for data-modulating and transmitting a bit sequence of binary data, wherein an HPSK data modulating part uses three successive bits (d0,d1,d2) to produce two symbols consisting of I and Q complex components, and further data-modulates the two symbols such that the phase difference therebetween is 90 degrees, thereby sequentially generating and wireless-transmitting symbols having the same signal point variation pattern as the HPSK spread sequence.
(FR)
L'invention concerne un appareil de transmission pour la modulation en données et la transmission d'une séquence de bits de données binaires, selon lequel une partie de modulation de données HPSK utilise trois bits successifs (d0, d1, d2) pour produire deux symboles consistant en des composants complexes I et Q, et en outre module en données les deux symboles de telle sorte que la différence de phase entre ceux-ci est de 90 degrés, de ce fait générant séquentiellement et transmettant sans fil des symboles ayant le même motif de variation de point de signal que la séquence étalée HPSK.
