Outer Bounds for Multiple Access Channels with Feedback using Dependence Balance
We use the idea of dependence balance to obtain a new outer bound for the capacity region of the discrete memoryless multiple-access channel with noiseless feedback (MAC-FB). We co...

Optimal Index and Data Allocation in Multiple Broadcast Channels
The issue of data broadcast has received much attention in mobile computing. A periodic broadcast of frequently requested data can reduce the workload of the up-link channel and f...

An Asymptotically Sum-Rate Optimal Precoding Scheme for MIMO Gaussian Broadcast Channel
—In this paper, we study the downlink precoding schemes for MIMO Gaussian broadcast channels (MIMO GBC). A novel low-complexity zero-forcing dirty-paper-coding (DPC) scheme, name...
