In this paper, we combine centralized dynamic-time division duplex (D-TDD) with interference alignment (IA) for a wireless network comprised of $N$ full duplex nodes. We maximize the performance of the proposed centralized D-TDD scheme utilizing IA in terms of rate region by optimizing the reception, transmission, simultaneous reception and transmission, and silence at each node in each time slot in addition to the choice of whether a node should treat the interference as noise or it should use IA. The problem of the rate region maximization of the wireless network is formulated as a non-convex optimization problem, whose optimal solution is found. The simulation results demonstrate that the proposed centralized D-TDD scheme utilizing IA achieves significant gains over the existing D-TDD schemes.

利用干扰对齐的集中动态时分双工

在本文中，我们将集中式动态时分双工 (D-TDD) 与干扰对齐 (IA) 相结合，用于无线网络 $N$ 全双工节点。我们通过优化每个时隙中每个节点的接收、传输、同时接收和传输以及静音，除了选择节点是否应该将干扰视为噪声或应使用 IA。将无线网络的速率区域最大化问题表述为非凸优化问题，并找到其最优解。仿真结果表明，所提出的利用 IA 的集中式 D-TDD 方案比现有的 D-TDD 方案取得了显着的收益。
