Dequantization of a signal from two parallel quantized observations
Vojtěch Kovanda, Pavel Rajmic · arXiv (Cornell University) · 2024
We propose a technique of signal acquisition using a combination of two devices with different sampling rates and quantization accuracies. Subsequent processing involving sparsity regularization enables us to reconstruct the signal at such a sampling frequency and with such a bit depth that was not possible using the two devices independently. Objective and subjective tests show the superiority of the proposed method in comparison with alternatives.
