Nice to see a Chinese face here :)

Since you have done a lot of research, you should feel *confident* it is
feasible. I was involved in a MIMO project when I was doing my bachelor
thesis about two years ago, and we implemented a 2x2 MU-MIMO system with
CSI feedback and transmit precoding on USRP and GNU Radio. However, it
only implements downlink transmission and lacks of OFDM (so just narrow
band). Nevertheless it proved the feasibility.  Unfortunately we hadn't
furthered that research since then. It's really glad to see you want to
explore it tightly with upstream. I attach the link to my thesis report
(it is in Chinese) below, and hopefully you will find something helpful.

Hi Zhao,

It is very nice to receive your reply, seems I'm not alone here. 
Your thesis is written with clarity and meaning, which is certainly helpful me. Besides, you know, it really feels enjoyable to read some relevant materials in Chinese. :) 
Maybe we will have more discussion in the future.

Thank you,
Zhou
