Sentence examples for harvesting constraints from inspiring English sources
Most recently, in [5], the authors studied MIMO beamforming with partial channel state information (CSI) under energy harvesting constraints.
Harvesting constraints due to lack of owner cooperation, biodiversity considerations or site constraints were not included in any of the scenarios tested.
As for this energy harvesting-wireless sensor networks (EH-WSN), the main challenge is to maximize its working performance under energy harvesting constraints, so studies on the MAC protocol, routing protocol, and cross layer optimization also obtain lots of achievements [4 10].
To satisfy the energy harvesting constraint of f 1, ∥g H w∥2+1≥Q should be guaranteed.
If Q>g H S ∗ g+1, it follows that P B is limited by the the energy harvesting constraint.
If Q ∗≥Q, it is easily known that P B is not limited by the energy harvesting constraint.
We designed zero-forcing-based joint information beamforming and energy beamforming to maximize the secret rate under the transmit power constraint and the energy harvesting constraint.
We aim to maximize the achievable secrecy rate at the IR by designing the transmit covariances of the WD and ET under the energy harvesting constraint of WD and transmit power constraints of WD and ET, respectively.
On the other hand, baseline II maximizes the weighted energy efficiency of the system with respect to W and without taking into account the minimum energy harvesting constraint in the optimization problem.
For the secure SWIPT without artificial noise, if the energy harvesting constraint 1≤Q≤g H S ∗ g+1, P B is equivalent to: begin{array}{*{20}l} mathbf{PB},-,1 underset{boldsymbol{S}succeq mathbf{PB},-,1 underset{boldsymbol{S}succeql{h}{maxthrm{H}}boldsymbol{S}boldsymbol{h}right),-,log_{2}left(1,+,boldsymbol{g}^{mathrm{H}}boldsymbol{S}boldsymbol{g}right) end{array} (15).
As opposed to battery-limited devices that are subject only to a power constraint or a sum energy constraint, EH transmitters are, in addition, subject to energy-harvesting constraints, i.e., sporadic arrival of the harvested energy in limited amounts performs a totally different energy available profile in each block.
