Reliable Wireless Broadcasting with Near-Zero Feedback
We examine the problem of minimizing feedbacks in reliable wireless broadcasting, by pairing rateless coding with extreme value theory. Our key observation is that, in a broadcast ...

Distributed Multi-Cell Zero-Forcing Beamforming in Cellular Downlink Channels
Abstract— For a multiple-input single-output (MISO) downlink channel with ¢ transmit antennas, it has been recently proved that zero-forcing beamforming (ZFBF) to a subset of (a...
