Power Splitting and Power Allocation for Energy Harvesting Multi-antenna Relay Networks in the Presence of CSI Errors

Zhi-hui LIU, Ye MIAO, Zi-jing CHENG
Adaptive power splitting and power allocation can provide a substantial performance gain in energy-hungry multi-antenna relay wireless networks when perfect channel state information (CSI) is available at relay. In the case when only imperfect CSI is available, the performance may significantly degrade,...
