Efficient interleaver/de-interleaver desigh for the turbo decoder in a 3g wcdma system

摘要

A device, such as an interleaver, a de-interleaver, or other devices, for interleaving or de-interleaving a signal within a wireless communication system. The device may interleave or de-interleave the signal spontaneously using a pseudo-random logic. Interleaving or de-interleaving the signal spontaneously may enable one or more features of the device to be enhanced. For example, less RAM may be required to interleave or de-interleave the signal, a die size of the device may be decreased, or other features may be enhanced. The device may receive a signal including a plurality of symbols. The plurality of symbols may be organized into one or more symbol blocks. While a number of symbols in the symbol blocks may vary from block to block, all (or substantially all) of the symbol blocks may be augmented to be of a fixed block length. Dummy bits may be used to augment the symbol blocks.
