Title
Multi-Antenna SWIPT Relaying Systems: Impact of Antenna Correlation and Channel State Information.
Abstract
This paper investigates the impact of antenna correlation on wireless powered dual-hop multi-antenna relaying systems with instantaneous channel state information (CSI) or statistical CSI at the relay. Considering the power-splitting architecture, we study the outage probability as well as the achievable diversity order of the system for amplify-and-forward protocol. Our results show that, antenna correlation itself does not affect the achievable diversity order, the availability of CSI at the relay determines the achievable diversity order. Full diversity order can be achieved with instantaneous CSI, while only unit diversity order can be achieved with statistical CSI. In addition, with instantaneous CSI, antenna correlation is detrimental in the moderate and high SNR regime while it results in a better performance when the operating SNR is low. On the contrary, antenna correlation is always beneficial with only statistical CSI.
