摘要：
Trellis coded quantization (TCQ) [1] is a new source coding technique based on ideas from trellis coded modulation (TCM). We present a vector generalization of TCQ, called trellis coded vector quantization (TCVQ), and experimental results showing its performance on the i.i.d. Gaussian source. For a given rate, TCVQ yields a lower distortion than TCQ at the cost of an increase in implementation complexity. In addition, TCVQ allows fractional rates, which TCQ does not.
