Optimal and Suboptimal Power Allocation Schemes for OFDM-based Cognitive Radio Systems
In this paper, we investigate an optimal power loading algorithm for an OFDM-based cognitive radio (CR) system. The downlink transmission capacity of the CR user is thereby maximiz...

Hybrid kinetic-MHD simulations in general geometry
We present a hybrid kinetic-MHD model consisting of 3 species, the bulk fluid ions and electrons, and a kinetic minority hot particle species. The 3 species equations are derived ...
