A method and receiver which provides, among other features, for resubtraction of an already subtracted signal in order to eliminate subtraction errors, termed re-orthogonalization, is described herein. According to exemplary embodiments, pairwise combinations of spreading codes are used to despread received composite signals. For example, these pairwise combinations can include a first spreading code associated with a signal that has already been subtracted and a second spreading code associated with a signal which is weaker than that associated with the first spreading code. In this way both resubtraction and subtraction are performed at the same time.
L'invention se rapporte à un procédé et à un récepteur qui a la fonction, entre autres, de resoustraire un signal déjà soustrait afin d'éliminer des erreurs de soustraction, procédé nommé ré-orthogonalisation. Selon certaines réalisations, des combinaisons par paires de codes d'étalement sont utilisées pour recompresser des signaux composites reçus. Par exemple, ces combinaisons par paires peuvent comprendre un premier code d'étalement associé à un signal qui a déjà été soustrait et un second code d'étalement associé à un signal plus faible que celui associé au premier code d'étalement. De cette façon, le resoustraction et la soustraction sont effectuées en même temps.
