Abstract
Optimal period rate matching for turbo coding. A means is provided herein by which a nearly optimal (e.g., optimal for one block size and sub-optimal for others) periodic puncturing pattern that depends on a mother code. Any desired rate matching can be achieved using the means and approaches presented herein to ensure an appropriate rate of an encoded block output from a turbo encoder so that the subsequently modulated signal generated there from has the appropriate rate. In addition, some embodiments can also employ shifting for another design level available in accordance with puncturing employed to provide for periodic rate matching. Selectivity can also be employed, such that, a first periodic puncturing pattern can be applied at a first time to ensure a first rate, and a second periodic puncturing pattern can be applied at a second time to ensure a second rate.
