Abstract

"In this work we study the performance of Tree-Structured Vector Quantizers (TSVQ) jointly designed with Forward Error Correction Code providing Unequal Error Protection (UEP) for the transmission of still images over noisy channels. Comparisons have shown that this scheme performs better than Channel Optimized Vector Quantizers (COVQ) scheme and is less affected by the channel distortion. The design of the TSVQ matched to the noisy channel is less complex than the design of COVQ and it has, in addition, a simpler implementation."
