Nonlinear Blind Identification with Three-Dimensional Tensor Analysis

الملخص EN

This paper deals with the analysis of a third-order tensor composed of a fourth-order output cumulants used for blind identification of a second-order Volterra-Hammerstein series.

It is demonstrated that this nonlinear identification problem can be converted in a multivariable system with multiequations having the form of Ax+By=c.

The system may be solved using several methods.

Simulation results with the Iterative Alternating Least Squares (IALS) algorithm provide good performances for different signal-to-noise ratio (SNR) levels.

Convergence issues using the reversibility analysis of matrices A and B are addressed.

Comparison results with other existing algorithms are carried out to show the efficiency of the proposed algorithm.
