Patent ID: 7916754

Claim:
A method of recovering a plurality of individual data streams from a composite data stream, the composite data stream having been formed by adding first discontinuous transmission (DTX) bits to the individual data streams, 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 method comprising; (a) receiving a current bit of one of the individual data streams in the composite data stream; (b) prior to storing the current bit in a memory space allocated to the one of the individual data streams, applying an inverse of the second bit reordering to identify whether the current bit is a second DTX bit and discarding the current bit without writing the current bit to the memory space if the current bit is the second DTX bit, wherein the second DTX bit is added to the data stream after the combining the individual data streams; (c) prior to storing the current bit in the memory space, applying an inverse of the second bit reordering to identify whether the current bit is a first DTX bit and discarding the current bit without writing the current bit to the memory space if the current bit is the first DTX bit; (d) storing the current bit in the memory space wherein the current bit is positioned within the memory space according to the first bit reordering; and performing steps (a) to (d) for each bit position in the composite data stream.
