A note on orthogonal discrete Bessel representation

The object of this note is to bring overview of discrete Bessel representations and to highlight their differences and similarities with both the discrete Fourier transform (DFT) methods and the finite basis/discrete variable representations (FBR/DVRs). Notably, the unpublished work of Corey and Le Roy deserves special attention. Also, the work of Littlejohn and Cargo is shown to yield an interesting derivation.
