Abstract
One embodiment of the present invention provides a system that resamples a quantized signal. During operation, the system receives the quantized signal. Next, the system smoothes and resamples the quantized signal to produce a resampled signal. The system then quantizes the resampled signal to produce a quantized resampled signal. For a given time point, the system determines a probability distribution for the resampled signal across quantization levels at the given time point by using information about the values of the resampled signal at neighboring time points. Note that the probability distribution specifies the probability that the resampled signal would be sampled at specific quantization levels. The system then uses the probability distribution to probabilistically select a quantization level for the resampled signal for the given time point.
