SEMI-BLIND DECONVOLUTION OF FINITE LENGTH SEQUENCE (Ⅱ)——NONLINEAR PROBLEM

【摘要】 <正> Following our previous paper, this paper studies the nonlinear deconvolution problems. In the z transform domain, by means of the relationship between the roots and the coefficients of a polynomial, several theorems are proposed to show that under certain conditions, by knowing only two end points of x(n) (or y(n)), x(n), y(n) can be uniquely specified from z(n). The sufficient.and neccessary conditions are given for a class of x(n), y(n) signals to be uniquely specified from z(n). An algorithm for nonlinear SBD is developed and the results of computer simulations are shown.更多还原
