A distributed multilayer architecture enabling end-user access to MIMO testbeds

We propose a distributed multilayer architecture that provides user access to a MIMO testbed at the convenient abstraction level for researchers. This novel architecture releases the user from the need of low-level programming, making the MIMO testbed accessible through high level software (i.e. Matlab or similar). The layers of this architecture are highly decoupled among them, allowing us to run each layer on a different PC. Also, each layer permits independent extension or customisation as needed, for example to implement new testbed features such as a feedback channel or to deploy multiuser MIMO scenarios.
