Abstract
A method for identifying the presence of an electronic transmission comprising detecting, by a detecting device, the presence of a burst of electromagnetic energy that results from the presence of an original carrier signal and transmitting, by a transmitting device, a spread spectrum meta-carrier signal within a portion of a bandwidth of the original carrier signal, wherein the meta-carrier signal contains information about the original carrier signal and is transmitted such that the meta-carrier signal occupies at least a portion of a bandwidth of the original carrier signal during the presence of the burst of electromagnetic energy.
