ABSTRACT:
Interleaving/de-interleaving of data is achieved by storing and subsequently retrieving portions of the data from circular buffers (60,70). The circular buffers (60,70) are addressed such that each circular buffer corresponds to an index of data (B.sub.i). Thus, data (80) is written into a circular buffer (60,70) using a first modulo scheme and read using a second modulo scheme, where the second modulo scheme is based on the interleaving scheme. An index array (20) is used to point to the appropriate entry in the circular buffers(60,70) to ensure a proper interleave/de-interleave process.
