Estimation of weighting-sequence matrices by correlation method
Y. Funahashi, Kentaro Nakamura · Electronics Letters · 1973
The pseudorandom binary sequence transformed by the Hadamard matrix is applied to the estimation of weighting-sequence matrices of multi-input and multioutput discrete-time systems. The method is based on the correlation analysis and matrix algebra. The weighting-sequence matrix is obtained directly from the measured-correlation matrix.
