Coding Schemes for User Cooperation in Low-Power Regimes
We consider the design of cooperation coding schemes for a two-user multi-access channel (MAC). In particular, we consider two block Markov coding schemes, namely, the multiplexed...

Cooperative mission planning for a class of carrier-vehicle systems
Abstract— In this work we focus on mission planning problems in scenarios in which a carrier vehicle, typically slow but with virtually infinite range, and a carried vehicle, wh...
