论文摘要
为了满足电信系统的延迟要求，在本文中，我们提出了一个合作网络，该网络在瑞利褪色渠道中具有短数据包传输。所需的继电器可以作为双向半双链（HD）或双向全双工（FD）实现。同样，为了更准确的满足和减少沟通延迟，请考虑使用短数据包发送和接收。有效容量适当地测量延迟约束下的传输速率。因此，这里被认为是绩效评估标准。使用双向继电器，两个节点同时使用继电器彼此交换。两个节点的优先级和要求不一定相同。因此，为了提高性能，将系统建模并解决为多目标问题。这样，网络中的可用功率被分配在继电器和两个节点之间，并且两个节点的有效容量最大化。根据不同的条件，计算了最佳的继电器和节点的分配功率。但是，由于复杂性和耗时的计算，提出了加快计算加速的近似方法。近似解决方案与最佳分配功率具有非常接近的性能。最后，在双向HD的性能和双向FD继电器的性能之间进行了各种比较。已经显示了多目标分配的改进，尤其是当继电器不在两个节点的中间时。
In order to satisfy the delay requirements of telecommunication systems, in this paper, we present a cooperative network with the short packet transmission in the Rayleigh fading channel. The desired relay can be implemented as a two-way half-duplex (HD) or a two-way full-duplex (FD). Also, for more accurate satisfaction and reduction of communication delays, sending and receiving with short packets is considered. Effective capacity appropriately measures the transmission rate under the delay constraint. Therefore, it is considered as a performance evaluation criterion here. With a two-way relay, two nodes exchange data with each other using a relay simultaneously. The priorities and requirements of the two nodes are not necessarily the same. Therefore, to increase performance, the system is modeled and solved as a multi-objective problem. In this way, the available power in the network is divided between the relay and two nodes, and the effective capacity of the two nodes is maximized. Depending on the different conditions, the optimal amount of allocated power to relay and nodes is calculated. However, due to the complexity and time consuming calculations, an approximate method which speeds up the calculation is presented. The approximated solution has a very close performance to the optimal allocated power. Finally, various comparisons have been made in different conditions between the performance of two-way HD and two-way FD relays. The improvement of multi-objective power allocation has been shown, especially when the relay is not located in the middle of two nodes.
