IMPROVED TURBO CODE INTERLEAVER FOR LOW FRAME ERROR RATE

摘要

At least one aspect of the invention provides a turbo encoder (104) having parallel first and second constituent encoders (202,206) and an interleaver (204) coupled as an input to the second constituent encoder to provide a pennutated 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 detain the information block is then passed to the second constituent encoder to improve the distance spectrum of the transmitted redundant data.
