摘要
A cost effective deinterleaving apparatus is selectively configurable for data streams interleaved according to one of a plurality of interleaving schemes. This is accomplished by providing a plurality of parameter sets for the apparatus with each set corresponding to a particular deinterleaving algorithm. A user is then able to selectively choose a particular deinterleaving algorithm with which to apply an input interleaved scheme. The low cost is achieved by reusing a single apparatus for all deinterleaving algorithms and changing only a few key parameters. Examples of applicable deinterleaving algorithms include Ramsey and Forney. Since any deinterleaver is also an interleaver, this invention is useful for interleaving as well.
