Error Exponent Regions for Gaussian Broadcast and Multiple-Access Channels
In modern communication systems, different users have different requirements for quality of service (QoS). In this work, QoS refers to the average codeword error probability experi...

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...
