Abstract
A receiver device for a modulated signal, suited in particular to a transmission system using a binary carrier phase modulation by means of a binary message on which a direct sequence spread spectrum operation has been carried out, this device comprising a first analog radio frequency part, transforming the signal received into a low-frequency, demodulated signal, said demodulated signal being applied to a second digital part of said device comprising an analog-to-digital converter and a filter matched to the spreading code used in order to delete the spreading applied to the original message, said device being characterized in that it includes an additional filtering unit, arranged between the analog-to-digital converter and the matched filter, said filtering unit implementing a stochastic matched filtering operation in order to improve the signal-to-noise ratio at the input of said matched filter.
