Re: [Discuss-gnuradio] Simulating MIMO-OFDM systems

[Martin Braun]

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.

Cheers,
