Moving average separation

A real symmetric polynomial Q(z) can be factored into the product A(z)A(z/sup -1/) if Q(z) is nonnegative on the unit circle. The authors pose a constrained minimization problem that results in the correct factorization in this case and gives an approximation to Q(z) if Q(z) does not satisfy the non...

Description
Summary:A real symmetric polynomial Q(z) can be factored into the product A(z)A(z/sup -1/) if Q(z) is nonnegative on the unit circle. The authors pose a constrained minimization problem that results in the correct factorization in this case and gives an approximation to Q(z) if Q(z) does not satisfy the nonnegativity condition.< >
