MIMO Propagation Modeling
Assess whether an environment can carry multiple parallel data streams.
How the workflow runs
Import the city geometry into AEDT — here, downtown Los Angeles from OpenStreetMap. Both MIMO terminals use connected slot arrays.
Configure one terminal as transmitter and one as receiver, with a single 5 GHz center frequency.
Obtain the channel matrix, compute its singular values, and apply a 2-D DFT to obtain the angular-domain channel.
Results
The singular-value spectrum and angular-domain channel together show whether the environment supports multiplexing or only diversity.
The singular values of the MIMO channel matrix reveal distinct non-interfering parallel channels. With only a single large singular value, as here, multiplexing several data streams is impractical — the environment lacks sufficient scattering.
In the angular domain, most receive power arrives from a single angle bin, confirming limited scattering at the receiver. The transmitter shows rich scattering across distinct angles that fade independently — enabling diversity and reducing outage probability.
