Abstract :
This paper is intended to investigate the bit rate allocation between source coding and channel coding rates when turbo codes are used to protect vector quantized images. The experimental results show that an appropriate bit rate allocation can lead to significant gains in the quality of the reconstructed images compared to an arbitrary bit rate allocation scheme.
