Interleaving has been largely adopted in communication systems as an effective way to spread adjacent symbols in transmission making them independent of the adjacent symbols in reception. In the case of fading channels adjacent symbols are normally affected by fading levels that are highly correlated, generating the so-called burst errors. In order to perform a good detection of the received symbols such bursts should be broken, spreading errors throughout the whole block. This task is performed by the channel interleaver.
