摘要
De-interleaving of forward-link paging or traffic channels is performed by implementing closed-form expressions that are equivalent to the table-based processing specified in the cdmaOne telecommunication specification. The implementation can be in either hardware or software or a combination of both. For each cdmaOne forward-link paging or traffic channel, the closed-form expression relates each interleaved symbol position to a corresponding de-interleaved symbol position, which is used to generate a de-interleaved symbol stream from the interleaved symbol stream. In one hardware implementation, the forward-link de-interleaver of the present invention has an address generation unit made from two modulo counters.
