Sparse Vector Recovery: Bernoulli-Gaussian Message Passing

open access: yes, 2017
Low-cost message passing (MP) algorithm has been recognized as a promising technique for sparse vector recovery. However, the existing MP algorithms either focus on mean square error (MSE) of the value recovery while ignoring the sparsity requirement, or

Novel Modeling and Filtering for Stochastic Switched Systems With Heterogeneous Behaviors

open access: yesIEEE Access, 2020
A novel heterogeneous behavior representation for linear stochastic switched system is proposed in the discrete-time domain. The switching modes of state evolution and measurement output are described by two random sequences with known probability ...

Mismatched Estimation in Large Linear Systems

open access: yes, 2015
We study the excess mean square error (EMSE) above the minimum mean square error (MMSE) in large linear systems where the posterior mean estimator (PME) is evaluated with a postulated prior that differs from the true prior of the input signal.

Analysis and application of minimum variance discrete time system identification [PDF]

open access: yes
An on-line minimum variance parameter identifier is developed which embodies both accuracy and computational efficiency. The formulation results in a linear estimation problem with both additive and multiplicative noise.

Semi-blind adaptive beamforming for high-throughput quadrature amplitude modulation systems

open access: yes, 2010
A semi-blind adaptive beamforming scheme is proposed for wireless systems that employ high-throughput quadrature amplitude modulation signalling. A minimum number of training symbols, equal to the number of receiver antenna arrays elements, are first ...
