Joint network coding and beamforming techniques for downlink channels
We propose a joint optimization of Network Coding and MIMO techniques to improve the downlink channel throughput of a wireless base station. Specifically, we consider a MIMO base...

Source-Channel Diversity for Parallel Channels
We consider transmitting a source across a pair of independent, nonergodic channels with random states (e.g., slow-fading channels) so as to minimize the average distortion. The ge...

Two-Hop Two-Path Voice Communications Over a Mobile Ad-Hoc Network
Abstract— We consider two-hop communication of a delaysensitive, memoryless Gaussian source over two independent paths in an ad-hoc network. To capture the behavior an ad-hoc net...

Using Antenna Array Redundancy and Channel Diversity for Secure Wireless Transmissions
— The use of signal processing techniques to protect wireless transmissions is proposed as a way to secure wireless networks at the physical layer. This approach addresses a uniq...
