Efficient Beamspace Downlink Precoding for mmWave Massive MIMO
We investigate efficient downlink precoding for all-digital downlink mmWave massive MIMO, with the number of users scaling with the number of antennas. […]
Critical points to determine persistence homology
Computation of simplicial complexes of a large point cloud often relies on extracting a sample, to reduce the associated computational burden. The […]
Incremental and diffusion compressive sensing strategies over distributed networks
Compressive sensing (CS) has been widely used in wireless sensor networks (WSNs). In WSNs, the sensors are battery-powered and hence their communication […]
