论文摘要
能源效率（EE）在未来的无线通信网络中起关键作用，并且在低SNR制度中很容易实现高EE性能。在本文中，通过使用二维资源分配，为在低SNR制度中工作的MIMO无线通信系统提出了一种新的高EE方案。首先，我们根据传输功率与SNR之间的关系定义高EE区域。为了满足高EE区域的约束，需要频率和空间维度。除了分别分析它们外，我们决定将频率和空间维度视为一个单位，并提出了二维方案。此外，考虑到高EE领域的通信可能会导致通信质量的下降，我们将服务质量（QoS）的约束添加到考虑中，并根据有效能力得出相应的EE绩效。我们还得出了一个近似表达式，以简化复杂的EE性能。最后，我们的数值结果证明了所提出的方案的有效性。
Energy efficiency (EE) plays a key role in future wireless communication network and it is easily to achieve high EE performance in low SNR regime. In this paper, a new high EE scheme is proposed for a MIMO wireless communication system working in the low SNR regime by using two dimension resource allocation. First, we define the high EE area based on the relationship between the transmission power and the SNR. To meet the constraint of the high EE area, both frequency and space dimension are needed. Besides analysing them separately, we decided to consider frequency and space dimensions as a unit and proposed a two-dimension scheme. Furthermore, considering communication in the high EE area may cause decline of the communication quality, we add quality-of-service(QoS) constraint into the consideration and derive the corresponding EE performance based on the effective capacity. We also derive an approximate expression to simplify the complex EE performance. Finally, our numerical results demonstrate the effectiveness of the proposed scheme.
