Abstract From the Canadian patent

Multiple stage interleaving through a memory matrix is utilized to separate adjacently disposed bits from bytes of digital information, in a reorganized bit stream. At least two stages of interleaving are required for the preferred embodiments of the invention which achieves a bit separation distance equal to the bit capacity of a plurality of either the matrix columns or rows, with that plurality being the number of adjacently disposed bits in each byte of digital information.
