Title (EN) APPARATUS FOR PROVIDING INCREASED DATA RATES WITHIN EXISTING MODULATION SYSTEMS
(FR) DISPOSITIF PERMETTANT D'ACCELERER LES DEBITS BINAIRES DANS DES SYSTEMES DE MODULATION EXISTANT
Abstract: front page image
(EN)A method for increasing data rates within a modulated signal is disclosed. Initially, a first and second bit streams are interleaved together to form an interleaved output bit stream. The interleaved output bit stream is modulated in a manner such that upon demodulation of the interleaved output bit stream according to an FSK modulation scheme only the first bit stream is recovered, and upon demodulation of the interleaved output bit stream according to a second modulation scheme, both the first and second bit streams are recovered.
(FR)Cette invention a trait à une technique visant à accélérer des débits binaires dans un signal modulé. Un premier et un second train de bits sont, tout d'abord, entrelacés afin de former un train entrelacé de bits de sortie. Ce train entrelacé est ensuite modulé, d'une part, de manière qu'après sa démodulation selon un mécanisme de modulation par déplacement de fréquence (MDF), on ne récupérer que le premier train et, d'autre part, de manière qu'après sa démodulation selon un second mécanisme de modulation, il soit possible de récupérer les deux trains de bits.
