LR-aided MMSE lattice decoding is DMT optimal for all approximately universal codes
Joakim Jalden, Petros Elia
Currently for the nt x nr MIMO channel, any explicitly constructed space-time (ST) designs that achieve optimality with respect to the diversity multiplexing tradeoff (DMT) are kno…

When Network Coding and Dirty Paper Coding meet in a Cooperative Ad Hoc Network
Nadia Fawaz, David Gesbert, Merouane Debbah
We develop and analyze new cooperative strategies for ad hoc networks that are more spectrally efficient than classical DF cooperative protocols. Using analog network coding, our s…

Quantized vs. Analog Feedback for the MIMO Downlink: A Comparison between Zero-Forcing Based Achievable Rates
Giuseppe Caire, Nihar Jindal, Mari Kobayashi +1
We consider a MIMO fading broadcast channel and compare the achievable ergodic rates when the channel state information at the transmitter is provided by analog noisy feedback or b…
