Abstract：

In　order　to　improve　the　video　transmission　performance　in　Multiple-Input　Multiple-Output　Orthogonal　Frequency　Division　Multiplexing　(MIMO-OFDM)　system,　a　new　scheme,　which　integrates　Multiple　Description　Coding　(MDC),　Low　Density　Parity　Check　(LDPC)　coding　and　hybrid　space　time　coding,　is　proposed　in　this　letter.　In　particular,　a　hybrid　space　time　coding　algorithm　is　combined　with　LDPC　codes　to　perform　Unequal　Error　Protection　(UEP)　of　MDC　encoded　video　streams.　Comparing　with　the　UEP　transmission　with　only　LDPC　codes,　the　proposed　scheme　achieves　more　than　1dB　gain　in　terms　of　Signal　to　Noise　Ratio　(SNR)　when　the　Peak　Signal　to　Noise　Ratio　(PSNR)　of　reconstructed　video　is　above　30dB.　©　Science　Press　2007.
