I am interested in simulating various algorithms for signal processing in MIMO-OFDM based software-defined radios and cognitive radios.
In this context, I am curious to know if such simulations are possible with GNU Radio?
For example, I would like to have a set of users with MIMO channels between them. I want to find out the data rates at the receiver for various settings of the MIMO-OFDM parameters.
If GNU Radio is not the right tool, can you please suggest if any other such tool (not MATLAB type) is available?
