Abstract
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.
