Resource Overview
This MATLAB package implements the blind identification algorithm for MIMO systems using second and higher-order output statistics. The core file "mimo_main.m" contains the complete implementation featuring system modeling, statistical analysis, and result visualization capabilities.
Detailed Documentation
This package provides MATLAB implementation of the blind identification algorithm presented in the referenced papers. The primary script "mimo_main.m" implements the complete algorithm workflow, which includes system modeling, statistical computation of output signals, and blind parameter estimation. The code is designed to identify Multiple-Input Multiple-Output (MIMO) systems by analyzing second-order and higher-order statistics of the output signals, under the assumption that input signals are white. The implementation features automated result visualization that generates comparative figures showing original system parameters versus estimated values, along with statistical analysis plots. Key functions handle covariance matrix computation, higher-order moment extraction, and iterative optimization for system parameter convergence.
