Abstract: front page image
(EN)The invention discloses a method and an apparatus for eliminating non-orthogonal channel interference. The method includes: in a first time sequence, correlating a non-orthogonal signal with a received signal to acquire a first correlation value (101); in the first time sequence, correlating a known orthogonal signal with the received signal to acquire a second correlation value (102); and subtracting a reconstructed signal, which is acquired from the first correlation value and the second correlation value, from the received signal (103). The present invention can be applied in a communication system with a non-orthogonal channel, and increase the performance of eliminating the non-orthogonal channel interference.
(FR)L'invention porte sur un procédé et un appareil d'élimination de brouillage de canal non orthogonal. Le procédé consiste à : dans une première séquence temporelle, corréler un signal non orthogonal à un signal reçu afin d'acquérir une première valeur de corrélation (101); dans la première séquence temporelle, corréler un signal orthogonal connu au signal reçu afin d'acquérir une seconde valeur de corrélation (102); et soustraire un signal reconstruit, qui est acquis à partir de la première valeur de corrélation et de la seconde valeur de corrélation, au signal reçu (103). La présente invention peut être appliquée dans un système de communication à canal non orthogonal, et augmenter les performances d'élimination du brouillage de canal non orthogonal.
