There have been a number of methods to generalize existing classes of multilinear functions with a view to improving the power and flexibility of analysis for PPS [16], such as the generalized representation of phase derivatives (GRPD) [17], the generalized high-order phase functions (GHOPF) [18].
where <p, q> = [bar][p.sup.T]q is the standard scalar product in [C.sup.n] (also used in [R.sup.n]), and the multilinear functions B(q, p) and C(p, q, r) are defined by
