Hi all, I'm Zhou, a graduate student now. I'm pretty interested in MIMO systems, especially Multiuser-MIMO, since it can increase the total throughput of the network significantly. But to the best of my knowledge, there seems no related standard blocks (gr-mimo or something) to achieve this in GNU Radio, few tutorials or examples are available either.
Currently, I'm working on a project to build a Multiuser-MIMO system based on OFDM. The basic requirement of this project is to implement Maximal-ratio combining (MRC) and Beamforming on both uplink and downlink sides. I notice that there existed an old GSoC project named "MIMO stuff" on the GNU Radio GSoC webpage a few months ago, but it is disappeared now. So I am wondering if "MIMO stuff" or some related work could be a part of GNU Radio GSoC 2014? If so, what kind of work it would be? Looking forward to get more details on it! Best regards Zhou
