Diversity-Multiplexing Tradeoff of Dynamic Harvest-and-Forward Cooperation
IEEE Wireless Communications Letters(2015)
摘要
We analyze the diversity-multiplexing tradeoff (DMT) of the dynamic harvest-and-forward (DHF) cooperation to clearly explain the achievable diversity order. Surprisingly, DHF cooperation with a relay that harvests energy from a wireless source achieves the same DMT as when the relay is connected to a fixed power supply, by supplying the energy harvesting (EH) period to be asymptotically small. For...
