Abstract-- We propose a joint source-channel coding scheme
for wireless communication systems with multiple transmit and
receive antennas. The source coder is realized by a multiple
description encoder that generates multiple bit streams of the
same source. Each description is then separately turbo coded and
transmitted using multiple antennas. For the receiver, we describe
a suitable iterative joint source-channel decoding technique that
exploits the correlations between the descriptions. Finally, we
present several examples that illustrate the performance of the
proposed system and compare it with other approaches.
