Energy-Efficient Transmission Strategies for CoMP Downlink - Overview, Extension, and Numerical Comparison
Kien-Giang Nguyen, Oskari Tervo, Quang-Doanh Vu +2
This paper focuses on energy-efficient coordinated multi-point (CoMP) downlink in multi-antenna multi-cell wireless communications systems. We provide an overview of transmit beamf…
Alternating Optimization for Capacity Region of Gaussian MIMO Broadcast Channels with Per-antenna Power Constraint
Thuy M. Pham, Ronan Farrell, Le-Nam Tran
This paper characterizes the capacity region of Gaussian MIMO broadcast channels (BCs) with per-antenna power constraint (PAPC). While the capacity region of MIMO BCs with a sum po…
Low-complexity Approaches for MIMO Capacity with Per-antenna Power Constraint
Thuy M. Pham, Ronan Farrell, Le-Nam Tran
This paper proposes two low-complexity iterative algorithms to compute the capacity of a single-user multiple-input multiple-output channel with per-antenna power constraint. The f…
Energy-Efficient Joint Unicast and Multicast Beamforming with Multi-Antenna User Terminals
Oskari Tervo, Le-Nam Tran, Symeon Chatzinotas +2
