Joint Optimal Power Allocation and Beamforming for MIMO-NOMA in mmWave Communications

IEEE Wireless Communications Letters, 2022
In this letter, we propose an optimal joint power allocation and beamforming for MIMO-NOMA in mmWave communications. In this method, to reduce the system overhead, we consider a random near random far (RNRF) pairing scheme in our NOMA data transmission ...

Optimal power allocation for NOMA-enabled D2D communication with imperfect SIC decoding

Physical Communication, 2021
The combination of device-to-device (D2D) communication with non-orthogonal multiple access (NOMA) is an efficient solution to enhance the spectral efficiency and connection density of beyond fifth-generation cellular networks.

Optimal Power Allocation for MIMO Underwater Wireless Optical Communication Systems Using Channel State Information at the Transmitter

IEEE Journal of Oceanic Engineering, 2021
For multiple-input–multiple-output underwater wireless optical communication (UWOC) systems with on–off keying modulation, we obtain the optimal power allocation policies that minimize the bit error rate (BER), subject to average power constraints.

Aggregated VLC-RF Systems: Achievable Rates, Optimal Power Allocation, and Energy Efficiency

IEEE Transactions on Wireless Communications, 2020
The aggregated visible light communication (VLC) and radio frequency (RF) system, which can be viewed as a heterogeneous multi-input-multi-output system, can improve data rate compared to the conventional RF communication systems. In this paper, we first

Optimal Reactive Power Allocation

IEEE Transactions on Power Systems, 1987
A systematic procedure is developed to locate reactive power devices in a power system based on a set of indices, that are based on overall system conditions. After identifying the desired locations, the cost of installation and number of reactive power devices, subject to any required practical and real economic constraints, are minimized.

Optimal power allocation for active and passive localization

2012 IEEE Global Communications Conference (GLOBECOM), 2012
Power resource allocation is crucial for localization since it affects not only the conventionally recognized lifetime, throughput, and covertness, but also localization efficiency of the network. In this paper, we present an optimization framework for range-based localization to improve the power efficiency and localization accuracy.
