摘要 为了在实际应用中降低分布式天线系统(distributed antenna system, DAS)的功耗,实现绿色移动通信的目标,该文研究了在同时包括传输功耗和电路功耗的实际功耗模型下,发送端仅知大尺度信道状态信息时的下行DAS系统的总功耗优化问题。采取了联合发送天线选择和功率分配方案,然后将原问题分解为一系列可用有效算法求解的子问题,最后在此基础上提出了一种低复杂度的联合排序选择和功率分配算法。仿真结果表明:所提算法在满足用户遍历容量需求时,可以使系统总功耗得到显著降低。该方案可以用较低的系统开销,实现DAS的实用性能提升。

Abstract:The power consumption in distributed antenna systems (DAS) is reduced for green mobile communications by optimizing the total power consumption in downlink DAS with only large-scale channel state information at the transmitter (CSIT) using a practical power consumption model including both the transmission power and the circuit power. The scheme combines transmit antenna selection and power allocation, decomposes the original problem into a series of sub-problems, each of which can be solved by efficient algorithms. The result is a low-complexity joint ordering selection and power allocation algorithm. Simulations show that the total power consumption is reduced considerably by this algorithm while satisfying the ergodic capacity requirements of the users. Thus, this scheme provides practical performance enhancement for DAS with low system overhead.
