A Closed Form Solution to Blind Equalization
 EURASIP Signal Processing
, 1994
"... In some recent papers new algorithms for blind adaptive equalization were proposed. These algorithms are based on the stochastic gradient method and thus can be regarded as a jblindj counterpart to the classic LMS (least mean squares) algorithms. It is wellknown that these algorithms show relativ ..."

coeOEcients can be uniquely derived from the eigenvectors of a speciøc 4thorder cumulant matrix of the received signal. By means of some examples it will be demonstrated that the eigenvector solution is near the ideal MSE (mean square error) solution. In der letzten Zeit wurden verschiedene neue
Blind Beamforming for Non Gaussian Signals
 IEE ProceedingsF
, 1993
"... This paper considers an application of blind identification to beamforming. The key point is to use estimates of directional vectors rather than resorting to their hypothesized value. By using estimates of the directional vectors obtained via blind identification i.e. without knowing the arrray mani ..."

Global mortality, disability, and the contribution of risk factors
 Global Burden of Disease Study. Lancet

A BLIND CHANNEL ESTIMATION STRATEGY FOR THE 2X1 ALAMOUTI SYSTEM BASED ON DIAGONALISING 4THORDER CUMULANT MATRICES
"... This paper presents a novel blind strategy to estimate the channel parameters in systems that make use of the well known Alamouti orthogonal spacetime code to achieve full diversity. The channel parameters are obtained by computing the eigenvectors of a matrix containing 4thorder cumulants of the ..."

Learning from demonstration
 Advances in Neural Information Processing Systems 9
, 1997
"... By now it is widely accepted that learning a task from scratch, i.e., without any prior knowledge, is a daunting undertaking. Humans, however, rarely attempt to learn from scratch. They extract initial biases as well as strategies how to approach a learning problem from instructions and/or demonstra ..."

By now it is widely accepted that learning a task from scratch, i.e., without any prior knowledge, is a daunting undertaking. Humans, however, rarely attempt to learn from scratch. They extract initial biases as well as strategies how to approach a learning problem from instructions and/or demonstrations of other humans. For learning control, this paper investigates how learning from demonstration can be applied in the context of reinforcement learning. We consider priming the Qfunction, the value function, the policy, and the model of the task dynamics as possible areas where demonstrations can speed up learning. In general nonlinear learning problems, only modelbased reinforcement learning shows significant speedup after a demonstration, while in the special case of linear quadratic regulator (LQR) problems, all methods profit from the demonstration. In an implementation of pole balancing on a complex anthropomorphic robot arm, we demonstrate that, when facing the complexities of real signal processing, modelbased reinforcement learning offers the most robustness for LQR problems. Using the suggested methods, the robot learns pole balancing in just a single trial after a 30 second long demonstration of the human instructor. 1.

Detection of Multicarrier Modulations Using 4thOrder Cumulants
 of Electrical Engineering, Czech Technical University in Prague, in
, 1999
"... This paper deals with modulation classification. Our goal is to discriminate singlecarrier (SC) modulations from multicarrier (MC) modulations of OFDM type. Because MCmodulations are asymptotically Gaussian, we propose here a detector using the statistical test of G. Giannakis and M. Tsatsanis [9 ..."
