The present invention relates to a multiple differential demodulator using a weighting value. The multiple differential demodulator according to the present invention includes a weighting value generator for integrating a real part and an imaginary part of a value acquired by multiplying one of a plurality of differentiated reception signals by a conjugated value of a differentiated PN code signal corresponding to a preset symbol, and determining the greater of the integrated real and integrated imaginary parts to apply a predetermined weighting value to the greater value, where the PN code signal is differentiated in the same fashion as the differentiated reception signals.

La présente invention concerne un démodulateur à différentiels multiples qui utilise une valeur de pesage. Selon cette invention, le démodulateur à différentiels multiples comprend un générateur de valeur de pesage pour l'intégration d'une partie réelle et d'une partie imaginaire d'une valeur acquise, en multipliant un de plusieurs signaux de réception différenciés par une la valeur conjuguée d'un signal de code pseudoaléatoire (PN) correspondant à un symbole prédéterminé, et en déterminant la plus grande valeur des parties réelles intégrées et des parties imaginaires intégrées afin d'appliquer une valeur de pesage prédéterminée à la valeur la plus grande, où le signal en code PN est différencié de la même manière que les signaux de réception différenciés.
