Optimal Power Allocation for SCMA Downlink Systems Based on Maximum Capacity

IEEE Transactions on Communications, 2019
Sparse code multiple access (SCMA) is a novel type of non-orthogonal multiple access technology that combines the concepts of CDMA and OFDMA. The advantages of SCMA include high capacity, low time delay, and high date rate.

Optimal Energy Efficient Power Allocation With User Fairness for Uplink MC-NOMA Systems

IEEE Wireless Communications Letters, 2019
The optimal energy efficient power allocation is investigated for the uplink multi-carrier non-orthogonal multiple access (MC-NOMA) system. Considering the user fairness, the power allocation is formulated as a maximization problem of the system weighted

Distributed Secondary Control for Power Allocation and Voltage Restoration in Islanded DC Microgrids

IEEE Transactions on Sustainable Energy, 2018
This paper presents a distributed secondary control scheme for accurate power allocation and voltage restoration in islanded dc microgrids. Conventionally the droop control function is employed in the primary control layer to realize power sharing among ...
