Resum
Lossless compression is often required for downloading data of scientific payloads in space missions. The consultative committee for space data systems (CCSDS) 121.0 recommendation on lossless data compression is a "de-facto" standard, and it has been used in several missions so far owing to the reasonable compression ratios achieved with low processing requirements. Although the Rice coder used by this standard is optimal when dealing with noiseless Laplacian-distributed data, its performance r...
