Joint trellis-coded quantisation/modulation
Zhaohui Cai, K. R. Subramanian, Tee Hiang Cheng · Electronics Letters · 2000
Joint trellis-coded quantisation (TCQ) and trellis-coded modulation (TCM) can achieve considerable signal-to-quantisation noise ratios with moderate complexity. TCM is replaced with turbo TCM (TTCM) and simulation results given which show that the new scheme can achieve the same performance as that possible using by trellis-coded scalar quantisation at an SNR slightly above the channel capacity bound.
