Some of the more popular are the Walsh, slant, and COSINE transforms. Another class of transform, called the number theoretic transform, can be applied to fast DFTs or convolutions.

WebDFT: $$ X[k] = \sum\limits_{n=0}^{N-1} x[n] e^{-j 2 \pi nk/N} $$ iDFT: $$ x[n] = \frac{1}{N} \sum\limits_{k=0}^{N-1} X[k] e^{j 2 \pi nk/N} $$ that is most fundamentally what the DFT is. it is inherently a periodic or circular thing. but the periodicity deniers like to say this about the DFT. it is true, it just doesn't change any of the above.
