In order to attain an optimally compressed, narrow pulse peak at the filter output of a correlation filter for the purpose of reception, the interfering secondary maxima of the autocorrelation function of binary codes must be as small as possible. The invention uses specially designed signal codes which are used to generate the associated complementary signal code from the received sequence by means of evaluation in the reception filter. The subsequent parallel formation of the autocorrelation functions of the received signal code and the complementary signal code exhibits secondary maxima having an opposite mathematical sign, thus resulting in the desired perfect pulse peak having secondary maxima which are equal to zero during summation at the filter output.
Afin de permettre d'obtenir, pour la réception, un pic d'impulsion étroit, comprimé de manière optimale, à la sortie d'un filtre de corrélation, les maxima secondaires perturbateurs de la fonction d'autocorrélation de codes binaires doivent être les plus faibles possibles. Selon l'invention, on utilise des codes de signaux présentant une forme particulière, à partir desquels le code de signal complémentaire associé est produit par évaluation dans le filtre de réception à partir de la séquence reçue. Lors de la formation parallèle consécutive des fonctions d'autocorrélation du code de signal reçu et complémentaire, les maxima secondaires présentent des signes opposés de sorte que le pic d'impulsion parfait souhaité présente des maxima secondaires nuls lors de la sommation à la sortie du filtre.
