The pseudorandom binary sequence is applied to the parameter estimation of discrete-time systems. The proposed method, based on correlation analysis and system theory, requires a smaller number of correlators than the other methods. The estimates of the parameters are shown to be asymptotically unbiased.
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.
