Performance Analysis and Optimal Power Allocation for Linear Receivers Based on Superimposed Training
Abla Kammoun, Karim Abed-Meraim
In this paper, we derive a performance comparison between two training-based schemes for Multiple-Input Multiple-Output (MIMO) systems. The two schemes are thetime-division multipl…
Constant Modulus Algorithms Using Hyperbolic Givens Rotation
Aissa Ikhlef, Redha Iferroujene, Abdelouahab Boudjellal +2
We propose two new algorithms to minimize the constant modulus (CM) criterion in the context of blind source separation. The first algorithm, referred to as Givens CMA (G-CMA) uses…
A new algorithm for complex non orthogonal joint diagonalization based on Shear and Givens rotations
Ammar Mesloub, Karim Abeb-Meraim, Adel Belouchrani
This paper introduces a new algorithm to approximate non orthogonal joint diagonalization (NOJD) of a set of complex matrices. This algorithm is based on the Frobenius norm formula…
Quasi-convexity of the asymptotic channel MSE in regularized semi blind estimation
Abla Kammoun, Karim Abed-Meraim, Sofiene Affes
In this paper, the quasi-convexity of a sum of quadratic fractions in the form is demonstrated where and are stri…
Exact Conditional and Unconditional Cramèr-Rao Bounds for Near Field Localization
Youcef Begriche, Messaoud Thameri, Karim Abed-Meraim
This paper considers the Cramèr-Rao lower Bound (CRB) for the source localization problem in the near field. More specifically, we use the exact expression of the delay parameter f…
