In this work we present a practical scheme for L-channel symmetric Multiple Description coding when one is only interested in receiving either a single description or all L descriptions. This scheme is based on oversampling and dithered Delta-Sigma quantization and is an extension of a scheme previously presented by Østergaard and Zamir. The oversampling(More)
Chronic inflammation is linked to atherosclerosis and Helicobacter pylori has been suggested to be an etiologic agent, although the evidence is equivocal. In this report, H. pylori was not detected by the polymerase chain reaction in atherosclerotic plaque from carotid endarterectomy samples.
The Nyquist theorem (for perfect reconstruction of a band-limited signal from its noiseless samples) depends, essentially, only on the average sampling rate. In contrast, reconstruction from imperfect samples strongly depends also on the sampling pattern. Specifically, when the samples are corrupted with independent noise, the reconstruction distortion is(More)
Random binning is an efficient, yet complex, coding technique for the symmetric L-description source coding problem. We propose an alternative approach, that uses the quantized samples of a bandlimited source as “descriptions”. By the Nyquist condition, the source can be reconstructed if enough samples are received. We examine a coding scheme(More)
