Abstract

In this paper, performance of turbo trellis coded modulation (turbo-TCM) is investigated in the Gilbert-Elliot channel model. We consider three methods for transmission through this channel. In the first method no channel interleaver is used, in the second method we employ a channel symbol interleaver after the mapping to make the channel memoryless. Finally, in the last method a bit interleaver is used before mapping to increase to diversity. For all cases, we have assumed that the channel state is known at the receiver.
