CA 2283848

Apparatus (10) and a method for receiving spread-spectrum signals is provided. The method includes the steps of detecting a noisy user signal from a spread- spectrum signal including at least a first user signal (including data therein) and at least one pilot signal, and removing an interference effect of the pilot signal on the first user signal from the noisy user signal thereby to create a noise reduced user signal (X'(n)).

La présente invention concerne un appareil et un procédé permettant de recevoir des signaux à spectre étalé. Le procédé de la présente invention consiste à détecter un signal utilisateur bruité dans un signal à spectre étalé comprenant au moins un premier signal utilisateur (contenant des données) et au moins un signal pilote, et à éliminer du signal utilisateur bruité l'effet de brouillage induit par le signal pilote sur le premier signal utilisateur, afin de générer un signal utilisateur à bruit réduit.
