Adaptive method and system for mapping parameter values to codeword indexes

摘要

Entropy by providing a coding method and system parameters are code words index representing the coded signal (20) it is mapped to the 128, the decoder 50 is able to reconstruct the coded signal from the code word index (128). The code words are at points were not aligned with or continuous manner in order for the parameters about one coding is inefficient parameter space is limited, the sorting step is used to sort into different groups of parameters, the parameter in the another group should be different ways to the code corresponding to the parameter being mapped to a codeword index word indexes are allocated in a manner based on a continuous and time. Sorting may be based on the absolute values of the parameters related to the selected value. In the decoding process, the codeword indexes are sorted into different groups based on values of codeword indexes in relation to also select value.
