Practical MU-MIMO experiments using SDRs
2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2017This paper provides an overview of a testbed created using software defined radios (SDRs) for a Multi-User MIMO experiment, with guidelines for extension for similar experiments. We perform our experiments in ORBIT grid with multiple USRPs. The proposed experiment can be easily recreated using multiple USRPs and Octoclock-G to achieve synchronization ...

MU-MIMO precoding for VLC with imperfect CSI
2015 4th International Workshop on Optical Wireless Communications (IWOW), 2015This paper investigates the performance of different precoding schemes for a multi-user MIMO VLC system with channel estimation errors, an assumption that is commonly neglected in the literature. In particular, dirty paper coding, channel inversion, and block diagonalization, are considered for interference mitigation under imperfect channel state ...

Security in Uplink MU-MIMO Networks
Proceedings of the Second International Conference on Internet-of-Things Design and Implementation, 2017Multiple-In-Multiple-Out (MIMO) offers great potential for increasing network capacity by exploiting spatial diversity with multiple antennas. Multiuser MIMO (MU-MIMO) further enables Access Points (APs) with multiple antennas to transmit multiple data streams concurrently to several clients. However, the uplink data transmission (from client to AP) of

MUTE: Sounding inhibition for MU-MIMO WLANs
2014 Eleventh Annual IEEE International Conference on Sensing, Communication, and Networking (SECON), 2014In this paper, we present the design, implementa- tion, and evaluation of the novel downlink Multi-User MIMO sounding protocol called MUTE. Our protocol decouples the sounding set selection used to collect Channel State Information (CSI), from the transmission set selection in order to minimize or even eliminate the overhead associated with sounding ...
