1. A method of communicating data comprising steps of:

  • (a) representing data in a first base representation;

    (b) converting the representation of the data in the first base to a representation of the data in a second base;

    (c) error correction encoding the representation of data in the second base; and

    (d) transforming coefficients of the error correction encoded representation of the data in the second base to obtain transformed encoded data meeting a specified constraint.
