<p>In order to deliver reliable information in a noisy signal environment spread user data is interleaved at the chip level. In particular, a spread sequence (212) enters a second interleaver (chip interleaver (208)). The interleaver (208) interleaves the input chips at the chip level. Within the interleaver (208), chips are individually input into a matrix which defines a predetermined size blocks of chips. For example, the chips are input into locations within the matrix so that the matrix is filled in a column by column manner. Chips are individually output from locations within the matrix so that the matrix is emptied in a row by row manner.</p> |
