Abstract :
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.
