Abstract
A method of contemporary use of digital and analog modulation on the same bandwidth is described. The phase of the carrier of an AM signal is modulated by a digital one. The rate of the digital signal depends on the RF bandwidth of the analog signal. The proposed technique can increase the bandwidth efficiency of existent communication systems. Measurements and results of a full hardware implementation will show the applicability of the method.
