Baseband image communication systems using code division multiple access are proposed. We investigate such a system using fixed-length pseudonoise (PN) codes and one using variable- length PN codes. We can find that the number of channels can be reduced when the latter is employed. Such a situation leads us to employ chaotic sequences, whose code-lengths can be arbitrarily chosen, for such variable-length PN codes.
