Resumen
A method to reduce coding complexity when the source alphabet is large, based on the alphabet partitioning is studied. The advantage of this scheme is that it is normally possible to find partitions that simultaneously allow large reductions in the coding complexity and with very small loss in the compression ratios. This partitioning technique is similar to definition of 'buckets' used for complexity reduction. The set numbers corresponds to the bucket number, and can also be used to simplify context-based coding. However, they have an additional purposes: they allow part of the information to be left uncoded, with obvious advantages in speed and complexity.
