Abstract
At least one aspect of the invention provides a turbo encoder having parallel first and second constituent encoders and an interleaver coupled as an input to the second constituent encoder to provide a permutated version of the binary data input to the first constituent encoder to achieve a low frame error rate. The interleaver is configured to parse the binary data input into an input block, determine a permutation vector, and rearrange the order of the binary data in the input block according to a set of predetermined permutation equations. The rearranged binary data in the information block is then passed to the second constituent encoder to improve the distance spectrum of the transmitted redundant data.
