Abstract：The author studied the QR factorization and generalized inverse of universal extended matrix.and the system parameter estimate is discussed.In addition,the formula of the QR factorization and generalized inverse of universal extended matrix were given.The results show that the algorithm is simple and fast,and it does not reduce the numerical accuracy.Another some results of paper[8,9] are generalized.

Key words： universal extended matrix QR factorization generalized inverse signal processing parameter estimate
