Outlier robust system identification: a Bayesian kernel-based approach
Giulio Bottegal, Aleksandr Y. Aravkin, Hakan Hjalmarsson +1
In this paper, we propose an outlier-robust regularized kernel-based method for linear system identification. The unknown impulse response is modeled as a zero-mean Gaussian proces…
Optimal input design for non-linear dynamic systems: a graph theory approach
Patricio E. Valenzuela, Cristian R. Rojas, Håkan Hjalmarsson
In this article a new algorithm for the design of stationary input sequences for system identification is presented. The stationary input signal is generated by optimizing an appro…
Adaptive experiment design for LTI systems
Lirong Huang, Håkan Hjalmarsson, László Gerencsér
Optimal experiment design for parameter estimation is a research topic that has been in the interest of various studies. A key problem in optimal input design is that the optimal i…
Application Set Approximation in Optimal Input Design for Model Predictive Control
Afrooz Ebadat, Mariette Annergren, Christian A. Larsson +2
This contribution considers one central aspect of experiment design in system identification. When a control design is based on an estimated model, the achievable performance is re…
On the Design of Channel Estimators for given Signal Estimators and Detectors
Dimitrios Katselis, Cristian R. Rojas, Håkan Hjalmarsson +2
The fundamental task of a digital receiver is to decide the transmitted symbols in the best possible way, i.e., with respect to an appropriately defined performance metric. Example…
The conservation of information, towards an axiomatized modular modeling approach to congestion control
C. Briat, E. A. Yavuz, H. Hjalmarsson +4
We derive a modular fluid-flow network congestion control model based on a law of fundamental nature in networks: the conservation of information. Network elements such as queues,…
Training Sequence Design for MIMO Channels: An Application-Oriented Approach
Dimitrios Katselis, Cristian R. Rojas, Mats Bengtsson +5
In this paper, the problem of training optimization for estimating a multiple-input multiple-output (MIMO) flat fading channel in the presence of spatially and temporally correlate…
