[0044] The technical solutions of the present invention will be further described below with reference to the drawings and specific implementations.
[0045] The present invention adopts a combination of software and hardware implementation method, in the case of using less resources, real-time generation of interleaving or de-interleaving addresses, its core idea is to divide the intra-code interleaver with a length of 40-5114 bits into Several mother interleavers of different lengths are used to construct the corresponding sub-interleavers through blank line pre-deletion technology, and on this basis, by deleting redundant half-line spaces, a Turbo code interleaver of a given length is realized. In the Turbo code interleaving and de-interleaving method of the present invention, the implementation device is divided into two parts: software and hardware. The software mainly realizes the calculation of one-time initialization parameters, and the hardware is used to complete repetit...
