Abstract : Huffman codes, comma-free codes, and block codes with shift indicators are important candidate message compression codes for improving the efficiency of communications systems. This study was undertaken to determine if these codes could be used to increase the thruput of the fixed very low frequency (FVLF) communication system. This applications involves the use of compression codes in a channel with errors. Keywords include: Comma-free codes, and Block codes.
