Concatenated Space­Time Block Coding With Trellis
Coded Modulation in Fading Channels

Abstract--Trellis coded modulation (TCM) is a bandwidth
efficient transmission scheme that can achieve high coding gain
by integrating coding and modulation. This paper presents an
analytical expression for the error event probability of concate-
nated space­time block coding with TCM which reveals some
dominant factors affecting the system performance over slow
fading channels when perfect interleavers are used. This leads
to establishing the design criteria for constructing optimal trellis
codes of such concatenated system over slow flat fading channels.
Through simulation, significant performance improvement is
shown to be obtained by concatenating the interleaved streams
of these codes with space­time block codes over fading channels.
Simulation results also demonstrate that these trellis codes
have better error performance than traditional codes designed
for single-antenna Gaussian or fading channels. Performance
results over quasi-static fading channels without interleaving
