摘要:
Turbo coding having combined turbo de-padding and rate matching de-padding. An approach is presented by which a singular module is operable to perform both zero bit de-padding and dummy bit de-padding in accordance with turbo encoding. Zero padding can be performed on an input information stream before undergoing turbo encoding. One or more of the 3 outputs from the turbo encoding module (e.g., systematic bits, parity 1 bits, and parity 2 bits) may then undergo dummy bit padding as well. Thereafter, these 3 streams (some or all of which may have undergone dummy bit padding) undergo sub-block interleaving. After all of these operations have taken place, a singular combined de-padding module that can be employed to perform de-padding any zero padded bits and any dummy padded bits from each of the three streams that have undergone the sub-block interleaving.
