Abstract
In a wireless communication system, a secure communication link is provided by producing a set of reference symbols selected from a modulation symbol constellation; generating a data-bearing pre-coding transform from information to be transmitted to a receiver; applying the data-bearing pre-coding transform to the set of reference symbols, thereby distorting the reference symbols with respect to the information, to produce a linear transformation signal; and transmitting the linear transformation signal to the receiver. The reference symbols are known at the receiver. The receiver removes the reference symbols from the linear transformation signal and decodes the data-bearing pre-coding transform.
