Energy Efficient Space–Time Line Coded Regenerative Two-Way Relay Under Per-Antenna Power Constraints
In multiple-input multiple-output (MIMO) systems, per-antenna power constraint (PAPC) has been considered to enhance the power efficiency of the multiple power amplifiers. Under PAPC, however, a conventional space-division multiple access (SDMA)-based two-way relay (TWR) method suffers a significant...
