Constrained VQ codebook design for noisy channels

open access: yesElectronics Letters, 2001
A codebook design approach for constrained vector quantisation using the Hadamard transform of channel transition probabilities is proposed. It is examined for quantisation of Gauss-Markov sources over channels with memory and compared with the generalised Lloyd algorithm.

Source Quantization and Coding over Noisy Channel Analysis

open access: yesMathematics
Recently, lossy source coding based on linear block code has been designed using the duality principle, i.e., the channel decoding algorithm is employed to realize the lossy source coding. However, the quantization structure has not been analyzed in this
