The advantage will also be that you can use the exact same code for
measurements. A lot of 'pure simuation' codes disregard too many
real-world phenomena and only use AWGN as distortion, but lack the means
to test over real channels.
As someone who spent a lot of time in academia, writing mixed
simulation/measurement suites among other things, I'd like to encourage
you to try this path of using GNU Radio.

Debarshi,
To be clear, since it sounds like you're new to GNU Radio, yes you can
implement MIMO-OFDM and it has been done by many people. There are
papers online that you can find detailing the journey, search for
'MIMO-OFDM with GNU Radio' or something similar. The details of this
will be up to you to implement (for example the "users" you speak of and
the logistics behind that).
v/r,
Rich

Hi Debarshi,
well, there's WiNeLo (Wireless Networks in the loop), which you can
attach multiple "virtual" SDR frontends to, and which uses GNU Radio
to model the channel and the SDRs.

Note: back when the paper was written, the channel simulation server
was based on a "simple" matrix; AFAIK I know it's using
fully-fledged GNU Radio by now.
Greetings,

Hi,
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?
Thank you for your time.
Regards,
Debarshi Kumar Sanyal
