Method, apparatus, and system for deinterleaving data

An apparatus comprising:

• a deinterleaver;
• the deinterleaver containing logic enabling:
• writing into a buffer having 172,032 metrics arranged into an 84 by 8 array of 16 by 16 blocks;
• wherein the buffer is partitioned into 4 subsets of rows;
• by writing data into the buffer in groups of 8 metrics;
• wherein each of the groups of 8 metrics are written in turn to each subset, in a column by column ordering;
• and
• rearranging data in each 16 by 16 block of arrays according to a table;
• wherein the table specifies the rearranged location of each metric in the 16 by 16 block.

A system comprising:

• one or more decoders;
• a deinterleaver;
• the deinterleaver containing logic enabling:
• writing data into a buffer having 172,032 metrics arranged into an 84 by 8 array of 16 by 16 blocks;
• wherein the buffer is partitioned into 4 subsets of rows according to a predetermined write sequence;
• applying a mapping table to change data in each of the 16 by 16 block of arrays according to a table;
• wherein the table specifies a mapping of the location for each metric in the 16 by 16 block;
• and
• reading the data out of the buffer to serve as input for a first decoder and a second decoder.
