A novel algorithm to control peak-power of the predistorted signal is proposed. The digital predistortion expands peak-power uncontrollably when power amplifers are operated at saturation. In order to control peak expansion, we introduce penalty of a barrier function into the cost function of linearization optimization. Our simulation demonstrates the effectiveness of peak-power controlling for the...
Closeness centrality is a basic centrality measure that characterizes how centrally located a node is, within a network, based on its distances to all other nodes. In this paper, we address the distributed computation of two variants of this measure, known as classic closeness and exponential closeness, which differ in how the distances are taken into account. For each variant, we construct continuous-...
Chinese enterprises have been conducting low-end processing for foreign brands. In recent years, they want to get rid of this high-pay low-income pattern and develop towards the high-end of the value chain. Most of them are transforming to service-focused enterprises that aim to provide customers with customized service. In service-focused enterprises, the human asset ¨C like industry experts, technology...
The problem of spacecraft relative position holding with limited thrust and thruster nonlinearity is investigated in this paper. The relative dynamic model with sampled-data measurement is established based on the Clohessy-Wiltshire (C-W) equations. Thruster nonlinearity and limited thrust constraint are taken into consideration. Then, the relative position holding problem is regarded as a sampled-data...
