A Two-Stage Precoding Method Based on Interference Alignment for Interference Channel Systems
— It was shown by Cadambe and Jafar that the interference alignment (IA) algorithm achieves the theoretical bound on degrees of freedom (DOF) for interference channel systems. Ho...

Broadcast Channels with Delayed Finite-Rate Feedback: Predict or Observe?
Most multiuser precoding techniques require accurate transmitter channel state information (CSIT) to maintain orthogonality between the users. Such techniques have proven quite fr...

Multiple-antenna multiple-relay system with precoding for multiuser transmission
Multi-hop relaying will play a central role in next generation wireless systems. In this paper a novel relaying strategy that uses multiple-input multiple-output (MIMO) relays in ...

Meeting Arbitrary QoS Constraints Using Dynamic Rate Shaping of Coded Digital Video
Abstract. We introduce the concept of Dynamic Rate Shaping, a technique to adapt the rate ofcompressed video bitstreams MPEG-1, MPEG2, H.261, as well as JPEG to dynamically varyi...
