Abstract
A layered space-time coding (STC) system is proposed to transmit video signal over wireless channels. An input video sequence is compressed and data-partitioned into layers with different priorities. Then, unequal error protection is incorporated with the space-time block coding to provide different levels of protection to the different layers. At the receiver, a minimum mean square error (MMSE) detector with interference cancellation (IC) is combined with the space-time decoder to reconstruct the signal effectively. We derive the analytic performance for error probability, and conduct the simulation for the transmission of the H.263 video bitstream. It is shown that the unequal error protection enhances the PSNR performance up to 10 dB in moderate signal to noise ratio environment.
