摘要

在本文中，我们考虑了在存在传输硬件缺陷的情况下具有多天线的解码和转发(DF)能量收集系统。继电器是能量受限的节点，使用时间开关架构从源信号中收集能量。为了简化中继选择的复杂度，采用了PRS-1和PRS-2两种部分中继选择方案。特别是，对于PRS-1方案，根据第一跳信道状态信息(CSI)选择辅助源到目的通信的最佳中继，而对于PRS-2方案，根据第二跳CSI选择最佳中继。为了评估硬件损坏对系统性能的影响，导出了中断概率和吞吐量的解析表达式。给出了蒙特卡罗模拟和有见地的讨论。

Performance analysis of energy-harvesting relay selection systems with multiple antennas in presence of transmit hardware impairments

In this paper, we consider a decoded-and-forward (DF) energy-harvesting system with multiple antennas in the presence of transmit hardware impairments. The relays are energy-constrained nodes that collect energy from the source signals using time-switching architecture. Two partial relay selection (PRS) schemes that are PRS-1 and PRS-2 are employed for simplifying the relay-selection complexity. In particular, for the PRS-1 scheme, the best relay that assists the source-to-destination communication is selected based on the first-hop channel-state-information (CSI) whereas for the PRS-2 scheme, the best relay is selected based on the second-hop CSI. To evaluate the effects of hardware impairments on system performance, the analytical expressions for outage probability and throughput are derived. Monte Carlo simulation and insightful discussion are provided.
