Abstract: After formulating the parameter estimation problem of MIMO systems with constraints on parameters of different equations, the least square estimates of parameters of the systems are obtained by using vector-dimension-augmenting technique and lagrange's method of multipliers. Based on the structural analysis of the estimating formula, analgorithm of the paramerter estimetes os given. The statistical properties of the estimates are discussed.

Key words: MIMO system, constraint, vector-dimension-augmenting technique, least square estimate
