Systems and methods consistent with embodiments of the present invention provide for efficient and compact encoding. In an exemplary method for associating a codeward with a symbol in a file, the frequency of occurrence of the symbols in the file is determined. Next, a threshold is determined. Explicit codewords are assigned to symbols with greater then the threshold. The remaining symbols are ordered in sequence and implicit codewords are assigned to all of remaining symbols. Finally, an encoding table associating the codeword for each symbol is generated.
