Help with module configuration

[RichBagdazian]

Hello,

I'm in need of some advise on the best mix of modules to be able to perform MIMO RF Processing.

My application needs to accept 4 RF input channels in the 800Mhz - 3Ghz range, Downconvert to baseband,

Perform signal processing via FPGA custom programming which will generate four new baseband output channels

then upconvert those four channels back to the same RF range as input. 

Could someone help steer me in the right direction to accomplish this?

Thanks in advance!

What's your bandwidth?

The Ettus device would be a good start. I am concerned whether there would be enough FPGA  resources for our algorithms.

Is there a feasible approach using the modular PXI architecture for MIMO processing that people use that is expandable as requirements grow/change?

Thank you!

There could be.  Given the frequency range and channel count you could go with VSTs and co-processors (for the FPGA resources) which may introduce latency.

If 2 channel MIMO is an option, one could start with a FlexRIO 5785 to develop some idea on FPGA utilization.  Maybe could work at a lower frequency band.

I do not know all of your constraints so it is difficult to select something more specific.
