Abstract
In this letter, a low-complexity suboptimal joint beamforming and power allocation (PA) design scheme for distributed multiple-input multiple-output (D-MIMO) system is proposed. With the objective of maximizing energy efficiency (EE), the developed suboptimal joint scheme can provide closed-form expressions of PA and beamforming. Compared with the existing schemes, the proposed suboptimal joint scheme needs no iterative calculation and yields a lower complexity. Moreover, it can achieve excellent EE quite close to that of the existing algorithms. Simulation results demonstrate the effectiveness and superiority of the proposed joint scheme.
Key findings
- The proposed scheme provides closed-form expressions for power allocation and beamforming.
- The scheme has lower complexity compared to existing schemes and does not require iterative calculations.
- The scheme achieves excellent energy efficiency, comparable to existing algorithms.
