I am starting to work in a mimo 2x1 configuration. As I've seen, the only implementation that already exists is in gnuradio sits in the trondeau branch. I've been trying to run the benchmark_ofdm_mimo for starters and I find several problems, because the compiler is looking for files from the main branch and not from the trondeau branch.I don't know if in order to work with this files it's just enough to copy them into the main branch or otherwise I should build gnuradio from the trondeau brach as well. I am not an expert at all when talking about programming and I don't want to mess with my previous work on the main branch so I don't know how I should proceed. It's maybe a silly problem but I would really appreciate any help. Actually I could really use any other advice referred to the work I am about to start . because as I've read on the mailing list, this mimo benchmark is not finished and people working with it is finding problems to get it to work, as I said before, I would really appreciate any help.
