发明名称 Method for coding low entrophy data
摘要 A method of lossless data compression for efficient coding of an electronic signal of information sources of very low information rate is disclosed. In this method, S represents a non-negative source symbol set, {s0, s1, s2, . . . sN-1} of N symbols with si=i. The difference between binary digital data is mapped into symbol set S. Consecutive symbols in symbol set S are then paired into a new symbol set GAMMA which defines a non-negative symbol set containing the symbols { gamma m} obtained as the extension of the original symbol set S. These pairs are then mapped into a comma code which is defined as a coding scheme in which every codeword is terminated with the same comma pattern, such as a 1. This allows a direct coding and decoding of the n-bit positive integer binary digital data differences without the use of codebooks.
