METHOD AND APPARATUS FOR INTERLEAVING WITHIN A COMMUNICATION SYSTEM

摘要

A method and apparatus for interleaving within a communication system is provided herein. More particularly parameters for a convolutional turbo code interleaver are provided, and interleaving takes place utilizing the new parameters. The new parameters generate interleavers that have the correct turbo code behaviors of improving performance with increasing block size and an error floor well below a block error rate of 10^-4. Furthermore, the parameters have no implementation impact. Interleaving in accordance with the preferred embodiment of the present invention can achieve a block error rate of 10^-4 at a signal to noise ratio that is at least 0.5 dB, and in some cases up to 1.3 dB, smaller than that which can be achieved with the code using the existing parameters.
