Abstract[English]
Apparatuses, methods, and systems are disclosed for MIMO EVM measurement using the pseudo-inverse. One method (700) includes receiving (705), from a transmitter (305), a multiple-layer transmission signal (310) via a propagation channel (315) that does not have full rank, where the multiple-layer transmission signal (310) is received using a MIMO receiver (325). The method (700) includes calculating (710) an EVM of the transmitter (305) using the pseudo-inverse of the channel matrix, where the pseudo-inverse that is derived using a reciprocal of non-zero diagonal elements.[French]
L'invention concerne des appareils, des procédés, et des systèmes de mesure d'EVM MIMO au moyen du pseudo-inverse. Un procédé (700) comprend la réception (705), en provenance d'un émetteur (305), d'un signal de transmission multicouche (310) par l'intermédiaire d'un canal de propagation (315) qui ne dispose pas de rang complet, le signal de transmission multicouche (310) étant reçu au moyen d'un récepteur MIMO (325). Le procédé (700) comprend le calcul (710) d'une EVM de l'émetteur (305) au moyen du pseudo-inverse de la matrice de canal, le pseudo-inverse étant dérivé au moyen d'une réciproque d'éléments diagonaux non nuls.
