—This paper considers distributed protocol design for joint sub-carrier, transmission scheduling and power management in uplink/downlink multi-cellular OFDMA wireless networks. T...
In this paper, cross-layer optimization approach is applied from video coding to the physical layer through Media Access Control (MAC) layer. We mainly focus on resource allocatio...
We present an algorithm based on convex optimization for constructing kernels for semi-supervised learning. The kernel matrices are derived from the spectral decomposition of grap...
