Left invertibility of discrete-time output-quantized systems: the linear case with finite inputs
This paper studies left invertibility of discrete-time linear output-quantized systems. Quantized outputs are generated according to a given partition of the state-space, while inp...

Robust precoding with Bayesian error modeling for limited feedback MU-MISO systems
We consider the robust precoder design for Multi-User Multiple Input Single Output (MU-MISO) systems where the Channel State Information (CSI) is fed back from the single antenna ...

Hardware acceleration of iterative image reconstruction for X-ray computed tomography
X-ray computed tomography (CT) images could be improved using iterative image reconstruction if the 3D conebeam forward- and back-projection computations can be accelerated signif...
