Optimal design of trellis coded quantization based on reliability information of turbo trellis coded modulation
説明
Turbo trellis-coded modulation (TCM) with code matched interleaver (CMI) is applied to develop a trellis coded quantization (TCQ). It can been shown that TCQ of memoryless Gaussian sources results in substantial improvement of performance with iterative decoding of turbo TCM and iterative optimization of minimum overall distortion between the source input and decoding output. Numerical results indicate substantial improvement of performance because optimal TCQ based on turbo TCM can be achieved at moderate to high signal-to-noise ratio (SNR) on an additive white Gaussian noise (AWGN) channel for a memoryless Gaussian source and a memoryless uniform source.
