Abstract
A data de-shuffler includes a buffer having a set of addressable locations for storing data and control circuitry for de-shuffling a sequence of shuffled data samples. The control circuitry stores a first data sample of the sequence of shuffled data samples at a first location in the buffer with a first address generated from an entry in a look up table and stores a second data sample at a second location in the buffer with a second address generated by incrementing from the first address by a selected incrementation value. The first and second locations in the buffer place the first and second samples in corresponding positions in an un-shuffled sequence of samples.
