Abstract
We study the waveform coding problem where the data source symbols have a distribution that is simultaneously highly peaked and very long tailed-a situation when the source entropy is small, but the coding process must deal with a very large number of symbols. This type of problem can be found, for example, in the lossless compression of medical images. Those images are digitized with 10-12 bpp, and they are commonly quite smooth
