A system and method for processing uncompressed high definition video data to be transmitted over a wireless medium is disclosed. In one embodiment, the system includes i) a plurality of convolutional encoders configured to input a plurality of video data streams and output a plurality of encoded data streams, respectively, wherein each data stream includes a plurality of data bits, ii) a group multiplexer configured to multiplex the plurality of encoded data streams into a multiplexed data stream, wherein the group multiplexer is further configured to multiplex a plurality of data bits together at one time and iii) a circulant bit interleaver configured to receive an m×n data stream block having n columns and m rows or convert the multiplexed data stream to an m×n data stream block, wherein the m×n data stream block comprises m×n data bits, and wherein the bit interleaver is further configured to interleave the received data bits diagonally and in a circulant manner with respect to the m×n block. The circulant bit interleaver interleaves the multiplexed data bits such that all data bits in one QAM symbol come from different convolutional encoders.
