Most coding schemes used in today's communication systems are designed for mem-
oryless channels. These codes break down when they are transmitted over channels
with memory, which is in fact what real-world channels look like since errors often
occur in bursts. Therefore, these systems employ interleaving to spread the errors so
that the channel looks more or less memoryless (for the decoder) at the cost of added
delay and complexity. In addition, they fail to exploit the memory of the channel
which increases the capacity for a wide class of channels. On the other hand, most
