The authors propose a channel-matched hierarchical table-lookup vector quantizer CM-HTVQ which provides some robustness against the channel noise. They use a finite-state channel to model slow fading channels and propose an adaptive coding scheme to transmit a source over wireless channels. The performance of CM-HTVQ is in general slightly inferior to that of channel-optimized vector quantizer COVQ the performances coincide in some cases however, the encoder complexity of CM-HTVQ is much less than the encoder complexity of COVQ.
