We first present an interpretation ofBAC in terms of a skewed binary map and then describe 7other possible chaotic maps which give similar Shannon optimalperformance as BAC. We then propose a modification of BACin which the overall length within the range [0,1) allocatedto each symbol is preserved, but the choice of map used toencode each symbol is based on a key.]
