Abstract

An apparatus and method for performing multiple dimensional Discrete Fourier Transforms. Data in R vectors of C elements is compressed and stored in a two-dimensional data structure, where an amount of compression is based on a respective weight of a windowing function that is applied to elements in that row when a column vector is read from the two-dimensional data structure memory circuit to create a windowed vector. A selected column vector is read, from the two-dimensional data structure, that contains a respective element from a selected column in each row of the two-dimensional data structure. A windowed vector is created by applying a windowing function to the selected column vector and a Discrete Fourier Transform is calculated of the windowed vector.
