An Adaptive UEP_BTC_STBC System for Robust H. 264 Video Transmission

A new adaptive UEP_BTC_STBC scheme is proposed to guarantee the robust video transmission according to the channel conditions. This scheme enhanced STBC (space-time block coding) by concatenating BTC code (block turbo code), both the good error correcting capability of BTC and the concurrent large diversity gain characteristic of STBC can be achieved simultaneously. Furthermore, by employing different BTC codes together with different modulation approaches, the scheme is capable of adapting to channel conditions and maximize end-to-end QoS of video transmission. Simulation result shows that the proposed adaptive scheme achieved significant improvement in delivered video quality according to channel condition.
