Low–high SNR transition in multiuser MIMO
Electronics Letters, 2015 Multiuser multiple‐input–multiple‐out (MU‐MIMO) plays a key role in the widely adopted 3GPP LTE standard for wireless cellular networks. Although exact and asymptotic sum‐rate results are well known, the problem of obtaining intuitive analytical results for medium signal‐to‐noise ratios (SNRs) is still not solved.

Performance analysis of distributed cluster-based MAC protocol for multiuser MIMO wireless networks
EURASIP Journal on Wireless Communications and Networking, 2011 It is known that multiuser multiple-input multiple-output (MIMO) communication can enhance the performance of wireless networks. It can substantially increase the spectral efficiency of wireless networks by utilising multiuser interference rather than ...

Multiuser SM-MIMO versus Massive MIMO: Uplink Performance Comparison
, 2013 In this paper, we propose algorithms for signal detection in large-scale multiuser {\em spatial modulation multiple-input multiple-output (SM-MIMO)} systems. In large-scale SM-MIMO, each user is equipped with multiple transmit antennas (e.g., 2 or 4 antennas) but only one transmit RF chain, and the base station (BS) is equipped with tens to hundreds of

Making multiuser MIMO work for LTE
21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2010 Underlining the viability of multiuser (MU) MIMO for future wireless communications as long term evolution (LTE), we propose in this paper a precoding strategy based on the low resolution LTE precoders which necessitates 2 bits feedback from the user equipment (UE).

Design and Experimental Validation of MIMO Multiuser Detection for Downlink Packet Data
EURASIP Journal on Advances in Signal Processing, 2005 In single-user MIMO communication, the first-order throughput scaling is determined by the smallest of the number of transmit and receive antennas. This typically renders terminals the constraining bottleneck.
