Abstract
In a wireless communication system, a secure communication link is provided by producing a set of reference symbol values selected from a modulation symbol constellation; generating a linear transformation operator from information to be transmitted to a receiver; applying the linear transformation operator to the set of reference symbol values, thereby distorting the reference symbol values with respect to the information, to produce a linear transformation signal; and transmitting the linear transformation signal to the receiver. The receiver decodes the linear transformation signal to receive the information.
