Exploiting Wireless Channel State Information for Throughput Maximization
— We consider the problem of scheduling packets over a number of channels with time varying connectivity. Policies proposed for this problem either stabilize the system when the ...

A Low-Complexity Iterative Channel Estimation and Detection Technique for Doubly Selective Channels
— In this paper, we propose a low-complexity iterative joint channel estimation, detection and decoding technique for doubly selective channels. The key is a segment-by-segment f...

Connectivity and Capacity of Multi-Channel Wireless Networks with Channel Switching Constraints
— This paper argues for the need to address the issue of multi-channel network performance under constraints on channel switching. We present examples from emergent directions in...

Effects of Imperfect Channel State Information on Achievable Rates of Precoded Multi-User MIMO Broadcast Channels with Limited F
—We consider multi-user MIMO broadcast channels with limited feedback. A recently proposed linear precoding technique, regularized block diagonalization (RBD), is used to mitigat...

Diversity Embedded Streaming Erasure Codes (DE-SCo): Constructions and Optimality
Streaming erasure codes encode a source stream to guarantee that each source packet is recovered within a fixed delay at the receiver over a burst-erasure channel. This paper intro...
