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

[Richard Bell]

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
