摘要:

能量效率是未来无线通信网络的关键,在低信噪比环境下实现高能量效率是很容易的。本文针对MIMO无线通信系统在低信噪比下工作的特点,提出了一种基于二维资源分配的高能效方案。首先,我们定义高EE区域的基础上的发射功率和SNR之间的关系。为了满足高能效地区的限制,需要同时考虑频率和空间维度。除了分别分析它们之外,我们决定将频率和空间维度作为一个单元来考虑,并提出了一个二维方案。此外,考虑到在高EE区域通信可能导致通信质量下降,我们加入了服务质量(QoS)约束的考虑,并推导出相应的EE性能的基础上的有效容量。我们还推导出一个近似表达式,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计划的有效性。

英文摘要:

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.
