Adaptive Digital Video Transmission with STBC over Rayleigh Fading Channels

In this study, we have proposed an algorithm assigned rates to MPEG2 video code and convolutional channel code, combined with space-time block coding (STBC) schemes, associated with BPSK/QPSK modulation method, based upon the feedback information from Performance Control Unit (PCU) over Rayleigh fading channel. The proposed scheme investigates a combined video source and channel coding together providing a uniform video transmission rate to achieve better system performance in wireless systems.
