On the computation of discrete Legendre polynomial coefficients
Proceedings of the 35th Midwest Symposium on Circuits and Systems, 1992
A new and fast method to find the discrete Legendre polynomial (DLP) coefficients is presented. The method is based on forming a simple matrix using addition only and then multiplying two elements of the matrix to compute the DLP coefficients.
