Patent ID: 7970595

Claim:
A device for simulating a multi-antenna radio channel, the device comprising: channel modules configured to incorporate propagation effects into channel signals which represent radio signals propagating along propagation paths, the channel modules being electrically connected to neighbour channel modules to form an (m,n) array configuration of the channel modules in which m and n are greater than 1, at least one (m,n) th channel module of the (m,n) array configuration being configured to receive a first (m,n−1) th channel signal from a (m,n−1) th channel module in a prior column of the (m,n) array configuration and a second (m−1,n) th channel signal from a (m−1,n) th channel module in a prior row of the (m,n) array configuration, the at least one (m,n) th channel module comprising: at least one processing resource configured to process the first (m,n−1) th channel signal according to a channel model, thus generating a processed (m,n) th channel signal; and a combiner configured to combine the processed (m,n) th channel signal and the second (m−1,n) th channel signal, thus generating a second (m,n) th channel signal, the at least one (m,n) th channel module further being configured to output the second (m,n) th channel signal, the (m,n) th channel module being configured to output the first (m,n−1) th channel signal as a first (m,n) th channel signal.
