论文摘要
在本文中，我们为无线网络提供了最佳的集中动态时间划分二链操作（D-TDD）方案，该网络由$ k $ $ $ $ $ $ $ $ $ k $的全副链节点组成，这些节点损害了自我干扰和添加性白色高斯噪声。作为一种特殊情况，当节点是半双链的以及无线网络由半双链和全双工节点组成时，我们还提供了最佳的集中式D-TDD方案。因此，我们在每个时间插槽中得出了接收，传输，同时接收和传输的最佳自适应调度，并在网络中的每个节点保持沉默，从而最大程度地提高了网络的速率区域。最佳集中式D-TDD的性能可以作为任何其他TDD方案的上限，这对于资格TDD方案的相对性能很有用。数值结果表明，所提出的集中式D-TDD方案比现有的集中式D-TDD方案实现了显着的利率。
In this paper, we derive the optimal centralized dynamic-time-division-duplex (D-TDD) scheme for a wireless network comprised of $K$ full-duplex nodes impaired by self-interference and additive white Gaussian noise. As a special case, we also provide the optimal centralized D-TDD scheme when the nodes are half-duplex as well as when the wireless network is comprised of both half-duplex and full-duplex nodes. Thereby, we derive the optimal adaptive scheduling of the reception, transmission, simultaneous reception and transmission, and silence at every node in the network in each time slot such that the rate region of the network is maximized. The performance of the optimal centralized D-TDD can serve as an upper-bound to any other TDD scheme, which is useful in qualifying the relative performance of TDD schemes. The numerical results show that the proposed centralized D-TDD scheme achieves significant rate gains over existing centralized D-TDD schemes.
