Abstract :
Based on the idea of unequal error protection, a novel error-correcting scheme for variable-length codes (VLC) is proposed. The synchronisation information in the VLC-coded bitstream acquires more protection without increasing coding overhead. Simulation results exhibit considerable gains of the proposed scheme over the traditional error-correcting scheme under a wide range of channel conditions.
