Data stream recovery

摘要

A method and processor for recovering a plurality of individual data streams from a composite data stream The composite data stream having been formed by first bit reordering the individual data streams with respect to themselves, combining the individual data streams and second bit reordering the combined individual data streams to form the composite data stream. The processor is arranged to for a current bit position in the composite data stream perform the steps of: (a) applying an inverse of the second bit reordering; (b) identifying to which individual data stream the current bit belongs; (c) storing the current bit in a memory space allocated to the identified individual data stream wherein the current bit is positioned within the memory space according to the first bit reordering; and performing steps (a) to (c) for each bit position in the composite data stream.
