Title (EN) SUPPRESSION OF MULTIPATH EFFECTS FOR RECEIVED SPS SIGNAL
(FR) SUPPRESSION DES IMAGES FANTÔMES POUR UN SIGNAL SPS REÇU
Abstract: front page image
(EN)The subject matter disclosed herein relates to suppressing the effects of multipath signals. For an example, a signal comprising at least one binary offset carrier (BOC) modulation signal is received. The BOC modulation signal is modulated with a pseudorandom noise sequence comprising a plurality of chips, wherein each of the chips has a set interval. The received signal is correlated with portions of the plurality of chips to provide a power signal and to remove at least a portion of a multipath component in the received signal from the power signal. The portions of the chips are less than the set interval.
(FR)L'invention concernée dans les présentes a trait à la suppression des signaux d'images fantômes. Par exemple, un signal comprenant au moins un signal de modulation de porteuse décalée binaire (BOC) est reçu. Le signal de modulation BOC est modulé avec une séquence de bruit pseudo-aléatoire comprenant une pluralité de bribes, chacune des bribes ayant un intervalle défini. Le signal reçu est mis en corrélation avec des parties de la pluralité de bribes pour fournir un signal de puissance et pour éliminer au moins une partie d'une composante à trajets multiples dans le signal reçu du signal de puissance. Les parties de bribes sont inférieures à l'intervalle défini.
