Capacity Improvement for Full Duplex Device-to-Device Communications Underlaying Cellular Networks

IEEE Access, 2018
In this paper, the capacity improvement of full-duplex (FD) device-to-device (D2D) underlaying cellular networks (CNs) is analyzed. A single-cell environment is considered with one half-duplex (HD) base station, multiple HD cellular user equipments (CUEs)

Optimal Power Allocation Based on Metaheuristic Algorithms in Wireless Network

Mathematics, 2022
An optimal power allocation is a fundamental challenge for massive multiple-input–multiple-output (MIMO) systems because the power allocation should be acclimated to time-varying channels and heavy traffic conditions throughout the communication network.

The Mine Locomotive Wireless Network Strategy Based on Successive Interference Cancellation

Sensors, 2015
We consider a wireless network strategy based on successive interference cancellation (SIC) for mine locomotives. We firstly build the original mathematical model for the strategy which is a non-convex model.
