The Dirty MIMO Multiple-Access Channel
, 2011
"... In the scalar dirty multiple-access channel, in addition to Gaussian noise, two additive interference signals are present, each known non-causally to a single transmitter. It was shown by Philosof et al. that for strong interferences, an i.i.d. ensemble of codes does not achieve the capacity region ..."

Optimality of beamforming in fading MIMO multiple access channels
- IEEE Transactions on Communications
, 2008
"... Abstract—We consider the sum capacity of a multi-input multi-output (MIMO) multiple access channel (MAC) where the receiver has the perfect channel state information (CSI), while the transmitters have either no or partial CSI. When the transmitters have partial CSI, it is in the form of either the c ..."

Selection of Transmit Antennas, Constellations and Powers for Correlated MIMO Multiple Access Channels
"... Abstract — A novel algorithm is presented to select the transmit antennas, constellations and distribution of total power of the users in a correlated multiple-input multiple-output (MIMO) multiple access channel. Given a target probability of symbol error, the spectral efficiency for each user and ..."

Optimal Operating Point for MIMO Multiple Access Channel with Bursty Traffic
"... Multiple antennas at the transmitters and receivers in a multiple access channel (MAC) can provide simul-taneous diversity, spatial multiplexing, and space-division multiple access gains. The fundamental tradeoff in the asymptotically large SNR regime is shown by Tse et al (2004). On the other hand, ..."

Optimality of beamforming for MIMO multiple access channels via virtual representation
- IEEE Trans Signal Process
, 2010
"... Abstract—In this paper, we consider the optimality of beamforming for achieving the ergodic capacity of multiple-input multiple-output (MIMO) multiple access channel (MAC) via virtual representation (VR) model. We assume that the receiver knows the channel state informa-tion (CSI) perfectly but that ..."

Power Allocation Games for MIMO Multiple Access Channels with Coordination
, 2009
"... A game theoretic approach is used to derive the optimal decentralized power allocation (PA) in fast fading multiple access channels where the transmitters and receiver are equipped with multiple antennas. The players (the mobile terminals) are free to choose their PA in order to maximize their indiv ..."

RATE REGION OF CORRELATED MIMO MULTIPLE ACCESS CHANNELS AND BROADCAST CHANNELS
"... In this paper, the rate region of large multi-antenna multiple access channels and broadcast channels are investigated. The propagation channels between transmitters and receivers are modelled as independent Gaussian with separable variance profiles. It is shown in particular that the large antenna ..."
