Signal Processing for MIMO Interference Networks

Minimax Duality for MIMO Interference Networks

A minimax duality for a Gaussian mutual information expression was introduced by Yu. An interesting observation is the relationship between cost constraints on the transmit covariances and noise covariances in the dual problem via Lagrangian multipliers. We introduce a minimax duality for general MIMO interference networks, where noise and transmit covariances are optimized subject to linear co...

Interference management in MIMO networks

To the memory of my mother, Rama Gaur ACKNOWLEDGEMENTS I would like to express my deep gratitude to Prof. Mary Ann Ingram for her invaluable advice and encouragement at every step of my PhD program. Without her unfailing support, patience, and belief in me, this thesis would not have been possible. Her contribution to this thesis goes well beyond her role as an academic supervisor and includes ...

Low-power MIMO signal processing

In this paper, we present a new adaptive error-cancellation (AEC) technique, denoted as multi-input–multi-output (MIMO)-AEC, for the design of low-power MIMO signal processing systems. The MIMO-AEC technique builds on the previously proposed AEC technique by employing an algorithm transformation denoted as MIMO decorrelating (MIMO-DECOR) transform. MIMO-DECOR reduces complexity by exploiting co...
