Abstract:
A method of reducing probability of detection and interception of a sub-carrier signal comprising encoding, using an encoder, information that is to be transmitted via the sub-carrier signal, modulating, using a modulator, the encoded information such that a modulated sub-carrier signal results, spreading, using a spreader, the modulated sub-carrier signal such that a spread sub-carrier signal results, and transmitting the spread sub-carrier signal at a frequency that is dynamic relative to an original carrier signal having a static frequency.
