Abstract
A data compression method, comprising: obtaining a plurality of values of a parameter and an occurrence probability of each of the plurality of values (S) comparing the occurrence probability with a predetermined threshold, wherein values with the occurrence probability less than the predetermined threshold are first set of values, and values with the occurrence probability greater than or equal to the predetermined threshold are second set of values (S), performing pretreatment on the first set of values (S), and encoding the second set of values and the pretreated first set of values (S). By means of the data compression method, the maximum codeword length can be effectively reduced, so as to reduce the requirements of a code table to the storage space.
