A method and apparatus for improving the transmission of an information signal having message information. A received information signal is formed from an information signal transmitted through an information channel. The received informa- tion signal has signal noise. The message information is removed from the received information signal to provide a symbol sequence that is then applied to a first filter to provide a first filtered signal. The power of the first filtered signal is determined and applied to a second filter to provide a second filtered signal representative of the signal noise of the received information signal.
L'invention concerne un procédé et un appareil servant à améliorer la transmission d'un signal d'information contenant un information de message. Un signal d'information reçu est formé à partir d'un signal d'information transmis par un canal d'information. Le signal d'information reçu comporte un bruit de signal. L'information de message est supprimée du signal d'information reçu afin de créer une séquence de symbole qui est ensuite appliquée à un premier filtre afin de créer un premier signal filtré. La puissance du premier signal filtré est déterminée et appliquée à un second filtre afin de créer un second signal filtré représentant le bruit de signal du signal d'information reçu.
