Abstract :
We propose a punctured trellis-coded quantization (PTCQ) scheme as the dual of a known punctured trellis-coded modulation (PTCM) scheme, and then generalize a combined trellis-coded quantization/modulation (TCQ/TCM) scheme to a combined PTCQ/PTCM scheme, with rates optimally allocated between source coding and channel coding to match the given channel signal-to-noise ratio (SNR). Simulation results show significant performance gain over the TCQ/TCM scheme at both low and high channel SNRs
