Design of UEP-based MSE-minimizing rateless codes for source-channel coding
This paper proposes a method to optimize the performance of tandem source–channel coding with respect to the mean-squared error by exploiting the unequal error protection coding...

Shrinkage algorithms for MMSE covariance estimation
We address covariance estimation in the sense of minimum mean-squared error (MMSE) when the samples are Gaussian distributed. Specifically, we consider shrinkage methods which are ...

Distributed average consensus in sensor networks with quantized inter-sensor communication
— The paper studies distributed average consensus in sensor networks, when the sensors exchange quantized data at each time step. We show that randomizing the exchanged sensor da...
