Compressed sensing based multi-user millimeter wave systems: How many measurements are needed?
Compressed sensing based multi-user millimeter wave systems: How many measurements are needed?
Millimeter wave (mmWave) systems will likely employ directional beamforming with large antenna arrays at both the transmitters and receivers. Acquiring channel knowledge to design these beamformers, however, is challenging due to the large antenna arrays and small signal-to-noise ratio before beamforming. In this paper, we propose and evaluate a downlink …
