摘要

我们提出了一种信号采集技术，它结合了两种具有不同采样率和量化精度的设备。随后的稀疏正则化处理使我们能够以这样的采样频率和比特深度重建信号，而这是单独使用两种设备无法实现的。客观和主观测试表明，与其他方法相比，所提出的方法更胜一筹。

Dequantization of a signal from two parallel quantized observations

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.
