Patent ID: 7490282

Claim:
An apparatus comprising: a turbo encoder to generate an encoded data block which includes voice and video; and a transmitter to transmit a data sub-block of the encoded data block within a time slot of a physical channel; a diagonal interleaver to equally distribute bits of the encoded data block over two or more interleaved data sub-blocks in a diagonal way over consecutive encoded data blocks; and a mapper to map bits of the two or more interleaved data sub-blocks to a predetermined number N of mapped data sub-blocks, wherein a predetermined number of bits X is to be equally mapped to the first and N th mapped data sub-blocks, a 2*X bits is to be equally mapped to the second and N−1 mapped data sub-blocks, a 3*X bits is to be equally mapped to the third and N−2 mapped data sub-blocks and 4*X bits is to be mapped to other mapped data sub-blocks.
