발명의 명칭: (EN) METHOD AND DEVICE FOR ESTIMATING CHANNEL QUALITY, AND RADIO RECEIVER
(FR) PROCÉDÉ ET DISPOSITIF D'ESTIMATION DE LA QUALITÉ DE CANAL, ET RÉCEPTEUR RADIO
(ZH) 信道质量估计方法、装置及无线接收机
요약서:
(EN) A method and a device for estimating channel quality, and a radio receiver, relating to the technical field of radio communications, solve the problem that channel quality estimation is not exact by reason that effective signal to interference plus noise ratio obtained by computing is not exact, in existing method for estimating channel quality. Because the sum of a channel matrix and an estimation error of the channel matrix is used during computing an equalization matrix, and the sum is a channel estimation matrix, the accuracy of effective signal to interference plus noise ratio obtained by computing using the equalization matrix is better, thereby enhancing the accuracy of the channel quality estimation. The method is mainly applied in a scene with a signal dataflow transmission and multi-receiving-antenna in a radio communication system.
(FR) Procédé et dispositif d'estimation de la qualité de canal, et récepteur radio, se rapportant au domaine technique des communications radio et résolvant le problème de l'inexactitude de l'estimation de la qualité de canal, due à l'inexactitude du rapport effectif signal/brouillage plus bruit obtenu par calcul, dans les procédés existants d'estimation de la qualité de canal. Comme la somme d'une matrice de canal et d'une erreur d'estimation de la matrice de canal est utilisée au cours du calcul d'une matrice d'égalisation, la somme étant une matrice d'estimation de canal, la précision du rapport effectif signal/brouillage plus bruit obtenu par calcul en utilisant la matrice d'égalisation est meilleure, ce qui renforce la précision de l'estimation de la qualité de canal. Le procédé est principalement appliqué dans le contexte de l'émission d'un flux de données de signal et d'antennes réceptrices multiples dans un système de communications radio.
(ZH) 一种信道质量估计方法、装置及无线接收机,涉及无线通信技术领域,解决了现有信道质量估计方法中,由于计算得到的有效信干噪比不准确导致的信道质量估计不准确的问题。由于在计算均衡矩阵时采用了信道矩阵及该信道矩阵的估计误差之和,该和即为信道估计矩阵,采用该均衡矩阵计算获得的有效信干噪比的准确性更高,从而提高了信道质量估计的准确度。该方法主要应用于无线通信系统中单数据流发送、多接收天线的场景。
