L'architecture de sondeur de canal MIMO basée sur le multiplexage par répartition en code (CDM) est efficace pour mesurer les canaux MIMO à évanouissement rapide. Cet article examine les séquences faiblement synchrones (LS), CAZAC, Kasami et chaotiques en tant que signaux de sondage dans l'architecture CDM. Après avoir comparé les performances de mesure de canal entre les séquences, il est conclu que les séquences LS sont les codes les plus appropriés pour les signaux de sondage. Cependant, comme les séquences LS présentent un inconvénient important dans la mesure où le nombre d'antennes d'émission est limité à moins de 4, nous proposons d'utiliser une architecture hybride combinant CDM et TDM pour supporter un plus grand nombre d'antennes d'émission. Les résultats de la simulation montrent que le schéma proposé peut améliorer les performances de mesure lorsque plus de 4 antennes d'émission sont utilisées.

Abstract: The code division multiplexing (CDM)-based MIMO channel sounder architecture is efficient at measuring fast fading MIMO channels. This paper examines loosely synchronous (LS), CAZAC, Kasami, and Chaotic sequences as probing signals in the CDM architecture. After comparing the performance of the channel measurement among the sequences, it is concluded that the LS sequences are the most appropriate codes for the probing signals. However, because LS sequences have a significant drawback in that the number of transmit antennas is limited to less than 4, we propose using a hybrid architecture combining CDM with TDM for supporting a greater number of transmit antennas. The simulation results show that the proposed scheme can improve the measurement performance when more than 4 transmit antennas are used.
