From: Study on adaptive compressed sensing & reconstruction of quantized speech signals
Average reconstruction SNR of adaptive quantization and nonadaptive quantization: (a) Average reconstruction SNR of voiced speech signals with respect to the TBD matrix and dense Gaussian matrix in the case of adaptive quantization and nonadaptive quantization. (b) Average reconstruction SNR of the entire testing speech signals with respect to the TBD matrix and dense Gaussian matrix in the case of adaptive quantization and nonadaptive quantization.
