If T(s)=M(s)D(s)⁻¹ is a RCMFD of T(s), then M(s) is a polynomial basis for 𝔛_t. If Q(s) is a greatest right divisor of M(s) then T(s)=◌̅M(s)Q(s)D(s)⁻¹, where ◌̅M(s) is a least degree polynomial basis of 𝔛_t [15].
text: When dealing with various polynomial bases up to a certain degree and with corresponding moments, any moment (with respect to any basis) can be expressed as a function of moments of the same or fewer orders with respect to an arbitrary basis.[…]As we already saw in Chapter 1, OG^([orthogonal]) moments are, unlike geometric and all other moments, coordinates of f in the polynomial basis in the common sense used in linear algebra.

text: For this purpose, a polynomial basis is used here, which consists of all monomials in the scheduling signals up to a fixed total order. Such a polynomial basis can be interpreted as the polynomial terms, which would appear in a multivariate Taylor approximation of the unknown scheduling function.

examples: text: When using polynomial bases, the first stage in computing the product of two elements of #92;mathbbF#95;#123;2ⁿ#125; is the multiplication of two polynomials of degree at most n-1 in #92;mathbbF#95;2#91;x#93;.

In this case, the GF(2ᵐ) multiplication is implemented in hardware using three algorithms for polynomial basis (PB) and three for gaussian normal basis (GNB).
text: In contrast to the case of normal bases considered in Theorem 5.1.9, the dual basis of a polynomial basis is usually not a polynomial basis.

5.1.13 Theorem [1265, 1298] Let #92;theta be a root of a monic irreducible polynomial f of degree m over K#61;#92;mathbbF#95;q, and let B#61;#92;#123;1,#92;theta,#92;theta²,#92;dots#92;theta#123;m-1#125;#92;#125; be the corresponding polynomial basis of F#61;#92;mathbbF#95;#123;qᵐ#125; over K. Then the dual basis B#42; of B is a polynomial basis if and only if f is a binomial and m#92;equiv 1#92;#33;#92;#33;#92;#33;#92;#33;#92;pmodp, where q is a power of the prime p.
5.1.14 Corollary There exists a dual pair of polynomial bases of #92;mathbbF#95;#123;qᵐ#125; over #92;mathbbF#95;q if and only if the following three conditions are satisfied:[…].
