Abstract
A recursive spectral factorization algorithm was developed by V. Solo (ibid., vol.34, no.10, pp.1047-1051, Oct. 1989) to be used with recursive instrumental variables for consistent estimation of the parameters of an ARMAX system, but the convergence of the spectral factorization algorithm is questionable. Herein, a modified adaptive spectral factorization algorithm is shown to converge and a general method for constructing convergent recursive solutions of nonlinear equations that are used to define parameter estimates is also presented
