A method of receiving signals in spread spectrum communication. The S/N characteristics are improved by reducing the influence of the colored noises of a com- paratively narrow band which are mixed in the process of transmission. Spread spectrum demodulation is performed by receiving the signal subjected to spread spectrum modulation by multiplying the data to be transmitted by a given series of spread codes, and by multiplying the received signal by a series of attenuation spread codes prepared by approriately attenuating or amplifying each chip of the series of the spread codes used for the modulation.
Procédé de réception de signaux en communication à étalement de spectre. Les caractéristiques signal/bruit sont améliorées par réduction de l'influence de bruits "colorés" d'une bande comparativement étroite qui sont mélangés au cours du processus de transmission. La démodulation a étalement de spectre s'effectue par réception du signal soumis à modulation à étalement de spectre grâce à la multiplication de données à transmettre par une série donnée de codes d'étalement, et à la multiplication du signal reçu par une série de codes d'étalement à atténuation préparés par atténuation approximative ou amplification comme il convient de chaque microplaquette de la série de codes à étalement utilisée pour la modulation.
