Abstract :
A novel approach for robust source transmission is presented where variable-length code (VLC) source and convolutional channel encoding are concatenated in parallel. Simulation results show that the proposed scheme leads to a strong increase in the signal-to-noise ratio at the decoder output compared to a serial concatenation of VLCs and channel codes
