ABSTRACT:
Interleavers used in fading channel applications can be matched to a particular trellis or block code being used. This matching can occur even in a particular transmission scheme such as TDMA. Matching both the interleaver and the code increases the separation between interdependent signal points and provides an improvement in error performance, without an increase in time delay over known interleaver design.
