Network-coded (NCed) automatic repeat request (ARQ) techniques have been shown to provide significant throughput improvements over basic ARQ systems in two-way wireless systems. Most results derived so far, however, used the assumption of no extra overhead. In practical systems, NCed-ARQ requires more information exchange between base-station and end-nodes, and therefore it is crucial to study the...
Physical layer network coding has attracted extensive theoretical interest, although relatively little research has been done in support of deployment to wireless networks where internode synchronization is difficult to achieve. In particular, wireless networks constructed with inexpensive and commercially available software defined radio technology, or more generally, radio front-end samplers connected...
Advanced cooperation strategies in multi-user multi-input multi-output (MU-MIMO) wireless communication systems could be facilitated by knowledge of global channel state information (CSI). Obtaining global knowledge of CSI in such MU-MIMO systems, where each user knows the CSI between every pair of users, would enhance cooperation amongst users and also improve the performance of such systems. In...
