| description | A method for second interleaving is disclosed. The method comprises: generating an interleaving address preset in an interleaving matrix for each input data, and writing the data into the interleaving matrix according to the interleaving address; initializing the interleaving address and reading out the data from the interleaving matrix according to the interleaving address; judging whether the reading operation on a column of data in the interleaving matrix is completed or not, if completed, then calculating the interleaving address of the next column in the interleaving matrix according to inter-column replacement rules; otherwise, obtaining the interleaving address by adding its own value to the column spacing; judging whether the reading operations on all data are completed or not, if completed, then the second interleaving ending; otherwise, returning to the step of reading out the data from the interleaving matrix according to the interleaving address, and repeating the above operation. A method for second de-interleaving and the corresponding apparatus for second interleaving and de-interleaving are also disclosed. |
