In this work, we investigate the minimum power of transmitting Gaussian multiterminal sources over the Gaussian multiple access channel (MAC) with bandwidth expansion. Distributed encoders observe the individual components of the multiterminal sources and attempt to describe them to a central decoder. Instead of assuming the sources and the channel have matched bandwidth, we consider the scenario...
We study the minimum energy of sending Gaussian multiterminal sources over the Gaussian multiple access channel (MAC). Distributed transmitters observe Gaussian multiterminal sources and describe their observations to a central decoder, which desires to reconstruct the sources under MSE constraints. We first lower bound the minimum energy by a cut-set argument which couples the transmitted signals...
