A method and apparatus is provided for encoding and decoding to facilitate coherent communication. In encoding, reference symbols are inserted into a stream of input data symbols (110) to form a reference coded stream of input data symbols (114). Subsequently, the reference coded stream of input data symbols are prepared for transmission over a communication channel by spreading the reference coded stream of input data symbols with a spreading code prior to transmission over the communication channel. In decoding, a received communication signal (120) is despread with a spreading cede to derive a stream of reference samples (132) and a stream of data samples (138). The channel response is estimated by utilizing the stream of reference samples (132). Finally, an estimated data symbol is detected from the stream of data samples (138) by utilizing the estimated channel response.

Procédé et appareil de codage-décodage assurant des télécommunications cohérentes. Pour le codage, des symboles de référence sont introduits dans un courant de symboles de données d'entrée (110) de façon à constituer un courant codé de référence de symboles de données d'entrée (114). Puis, ledit courant est préparé en vue de sa transmission sur un canal de télécommunications en le dispersant à l'aide d'un code de dispersion avant sa transmission. Pour le décodage, le signal reçu (120) est recombiné à l'aide d'un code de dispersion de façon à redonner un courant d'échantillons de référence (132) et un courant d'échantillons de données (138). La réponse du canal est estimée au moyen du courant d'échantillons de référence (132). Finalement, un symbole de données estimé est détecté dans le courant d'échantillons de référence (138) à l'aide de la réponse estimée du canal.
