N2 - The combination of jointly optimized rate compatible punctured convolutional (RCPC) codes and channel-matched tree-structured vector quantizers (CM-TSVQs) provides improved performance, in some cases, compared to the use of CM-TSVQs. The joint design algorithm allows unequal error protection to be applied to each bit of the CM-TSVQ output. Initial results show that the joint combination of soft-decoded RCPC codes and CM-TCVQs provides little rate-distortion advantage over soft CM-TSVQ at the first step of refinement. However, as further source refinements are made in the embedded designs, the joint combination provides an increasing performance improvement, relative to soft CM-TSVQ.
