We generalize Hermite interpolation with error correction, which is the methodology for multiplicity algebraic error correction codes, to Hermite interpolation of a rational function over a fieldfrom function and function derivative values.We present an interpolation algorithm that can locate and correcterrors at distinct argumentswhere at least one of the values or values of a derivative is incorrect. The upper boundEfor the number of suchis input. Our algorithm sufficiently oversamples the rational function to guarantee a unique interpolant. We samplefor,,distinct, whereis thej-th derivative of the rational functionf/g,,,, and where N = ∑ i = 1 n ( ℓ i + 1 ) ≥ D f + D g + 1 + 2 E + 2 ∑ k = 1 E ℓ k ;is an upper bound forandan upper bound for, which are input to our algorithm. The argumentscan be poles, which is truly or falsely indicated by a function valuewith the corresponding. Our results remain valid for fieldsof characteristic. Our algorithm has the same asymptotic arithmetic complexity as that for classical Hermite interpolation, namely.For polynomials, that is,, and a uniform derivative profile, our algorithm specializes to the univariate multiplicity code decoder that is based on the 1986 Welch-Berlekamp algorithm.
