Two known compression algorithms appropriate for communication are the LZW algorithm and the Arithmetic Coding. Both algorithms are adaptive and require no extra communication from the encoder to the decoder. We present a scheme to cascade these algorithms into an adaptive algorithm which achieves higher compression ratio and is appropriate for communication. Different variations of refining the cascading are tested to optimize the secondary compression.
