The invention provides a device for simulating a multi-antenna radio channel, a module and a method. The device comprises channel modules (4A to 4I) for incorporating propagation effects into channel signals which represent radio signals propagating along propagation paths, which channel modules (4A to 4I) are electrically connected to neighbour channel modules (4A to 4I) for forming an (m,n) array configuration. The (m,n)th channel module (500) is configured to receive a first (m,n-1)thchannel signal (508) and a second (m-1,n)th channel signal (506) and comprises: a processing resource (502) for processing the first (m,n-1)th channel signal (508) according to a channel model, thus generating a processed (m,n)th channel signal (514), and a combiner (504) for combining the processed (m,n)th signal (514) and the second (m-1,n)th channel signal (506), thus generating a second (m,n)th channel signal (512). The (m,n)th channel module (500) is further configured to output the second (m,n)th channel signal (512).

La présente invention a trait à un dispositif permettant de simuler un canal radio à antennes multiples, à un module et à un procédé associés. Le dispositif selon l'invention comprend des modules de canal (4A à 4I) permettant d'incorporer des effets de propagation dans des signaux de canal qui représentent des signaux radio se propageant le long de voies de propagation, lesdits modules de canal (4A à 4I) étant reliés par voie électrique à des modules de canal voisins (4A à 4I) afin de former une configuration de réseau (m,n). Le (m,n)e module de canal (500) est configuré de manière à recevoir un premier (m,n-1)e signal de canal (508) et un second (m-1,n)e signal de canal (506), et comprend : une ressource de traitement (502), destinée à traiter le premier (m,n-1)e signal de canal (508) d'après un modèle de canal, ce qui permet de générer un (m,n)e signal de canal traité (514) ; et un mélangeur (504), permettant de combiner le (m,n)e signal traité (514) et le second (m-1,n)e signal de canal (506), ce qui permet de générer un second (m,n)e signal de canal (512). Le (m,n)e module de canal (500) est également configuré de manière à produire le second (m,n)e signal de canal (512).
