Power Control for Underlay Full-Duplex D2D Communications Based on D. C. Programming

In recent years, with the massive increase in mobile smart devices, the demand for mobile services has also increased dramatically. In order to improve the network performance, full-duplex device-to-device (D2D) communications have drawn significant research interests. In this paper, a power control problem for underlay full-duplex D2D communications is formulated, which maximize the transmission rate of the full-duplex D2D link while fulfilling the minimum rate requirement of the cellular user. By using difference of convex (D. C.) programming, we can transform the problem into a convex optimization problem and find the optimal solution by using the iterative algorithm. Simulation results are given to prove the effectiveness of the algorithm.
