Network Efficient Power Control for Wireless Communication Systems [PDF]
The Scientific World Journal, 2014 We introduce a two-loop power control that allows an efficient use of the overall power resources for commercial wireless networks based on cross-layer optimization. This approach maximizes the network’s utility in the outer-loop as a function of the averaged signal to interference-plus-noise ratio (SINR) by considering adaptively the changes in the ...
