Energy and Spectral Efficiency of Very Large Multiuser MIMO Systems
Hien Quoc Ngo, Erik G. Larsson, Thomas L. Marzetta
A multiplicity of autonomous terminals simultaneously transmits data streams to a compact array of antennas. The array uses imperfect channel-state information derived from transmi…
On Optimal Link Activation with Interference Cancellation in Wireless Networking
Di Yuan, Vangelis Angelakis, Lei Chen +2
A fundamental aspect in performance engineering of wireless networks is optimizing the set of links that can be concurrently activated to meet given signal-to-interference-and-nois…
Constant Envelope Precoding for Power-Efficient Downlink Wireless Communication in Multi-User MIMO Systems Using Large Antenna Arrays
Saif Khan Mohammed, Erik G. Larsson
We consider downlink cellular multi-user communication between a base station (BS) having N antennas and M single-antenna users, i.e., an N X M Gaussian Broadcast Channel (GBC). Un…
Single-User Beamforming in Large-Scale MISO Systems with Per-Antenna Constant-Envelope Constraints: The Doughnut Channel
Saif Khan Mohammed, Erik G. Larsson
Large antenna arrays at the base station (BS) has recently been shown to achieve remarkable intra-cell interference suppression at low complexity. However, building large arrays in…
Achievable Outage Rate Regions for the MISO Interference Channel
Johannes Lindblom, Eleftherios Karipidis, Erik G. Larsson
We consider the slow-fading two-user multiple-input single-output (MISO) interference channel. We want to understand which rate points can be achieved, allowing a non-zero outage p…
