A closely related variant of the classical Cholesky decomposition is the LDL decomposition, Some indefinite matrices for which no Cholesky decomposition exists have an LDL decomposition with negative entries in D.
In a radar system, sampled aperture data are received from an antenna array.
However, the decomposition need not be unique when A is positive semidefinite.
The converse holds trivially: if A can be written as LL* for some invertible L, lower triangular or otherwise, then A is Hermitian and positive definite.
The results show that the theoretical and experimental MSE curves of the RI algorithm are in agreement. From 2011 to 2015, he worked as Assistant Professor at the Department of Electrical and Electronics Engineering, Mevlana University, Turkey.
Also, the MSE analysis of the RI algorithm in a nonstationary environment, where the optimum weight is assumed to be randomly changing about a fixed vector, is derived. He is currently working at the Department of Electrical Engineering at the American University of the Middle East, Kuwait.
for efficient numerical solutions and Monte Carlo simulations.
The issue is that the data changes as time goes on (hence the sample covariance matrix) and eigenvalues need to be recomputed.A novel analytical result which describes the learning behavior of the RI algorithm is obtained. From 2006 to 2010, he was a Research Assistant with the Electrical and Electronic Engineering Department, EMU. His research interests include Signal Processing, Adaptive Filters, Image Processing and Communications Systems. He has co-authored more than 50 technical papers in international journals and conferences. His current research interests include receiver design for wireless systems and adaptive filtering. It is shown that within limits of approximation, the excess mean-square-error (MSE) of the algorithm approaches zero and the RI algorithm converges to a lower steady-state MSE than the LMS algorithm. In 2010, he joined the Department of Electrical and Electronics Engineering at European University of Lefke as Senior Lecturer. His research interests include power electronics, control systems, and signal processing. Kukrer is a senior member of the IEEE, and a member of the Chamber of Electrical Engineers in North Cyprus.
