Patent

CA 2566091

A system for transmitting input data over a speech channel of a network, the system comprises: a modulator arranged to produce a modulated waveform signal transforming the data for transmission over the network; a channel compensation filter arranged to filter the modulated waveform signal after it has been transmitted over the speech channel to compensate for the response of the speech channel; and a demodulator arranged to retrieve the data from the filtered waveform signal.

L'invention concerne un système de transmission de données d'entrée sur une voie radiotéléphonique d'un réseau. Le système comprend un modulateur destiné à générer un signal oscillographique modulé transformant les données pour les transmettre sur le réseau; un filtre de compensation de voie destiné à filtrer le signal oscillographique modulé après sa transmission sur la voie radiotéléphonique afin de compenser la réponse de la voie radiotéléphonique; et un démodulateur destiné à récupérer les données du signal oscillographique filtré.
