Title (EN) MIMO DETECTION METHOD AND SYSTEM BASED ON CHANNEL CORRELATION
(FR) PROCÉDÉ DE DÉTECTION À ENTRÉES MULTIPLES-SORTIES MULTIPLES ET SYSTÈME BASÉ SUR UNE CORRÉLATION DE CANAL
Abstract: front page image
(EN)An OFDM symbol detection method is disclosed, comprising the steps of: receiving OFDM modulated symbols transmitted from multiple transmitting antennas; receiving information on correlation time and/or correlation bandwidth; performing channel estimation on each of a plurality of channels for the multiple transmitting antennas, and conducting smoothing processing on each channel estimation result according to said information on correlation time and/or correlation bandwidth, so as to obtain channel estimation averages of respective channels; and performing signal detection on the received OFDM symbols by using the channel estimation averages. Both time correlation and frequency correlation are considered in the method according to the present invention.
(FR)L’invention concerne un procédé de détection de symbole OFDM (multiplexage par répartition orthogonale de la fréquence), comprenant les étapes consistant à : recevoir des symboles OFDM modulés transmis par de multiples antennes d’émission ; recevoir des informations concernant le temps de corrélation et/ou la bande passante de corrélation ; réaliser une estimation de canal sur chaque canal d’une pluralité de canaux pour les multiples antennes d’émission, et réaliser un traitement de lissage sur chaque résultat d’estimation de canal selon lesdites informations concernant le temps de corrélation et/ou la bande passante de corrélation, de manière à obtenir des moyennes d’estimation de canal de canaux respectifs ; et réaliser une détection de signal sur les symboles OFDM reçus à l’aide de moyennes d’estimation de canal. A la fois la corrélation temporelle et la corrélation de fréquence sont prises en compte dans le procédé selon la présente invention.
