Abstract

Methods and systems for communicating data through a communication channel are disclosed. A first and a second signal portions are transmitted with the time delay between them corresponding to the value of the data that should be communicated through the communication channel. The communication of the data through the communication channel can be encrypted and concealed by modulating at least one of the first and second signal portions utilizing a certain modulation code, and transmitting the modulated signal portion through the communication channel with intensity in the order of, or below, the level of noise in the communication channel. In the reception path, signals received through the communication channel are processed to detect the reception of the first and second signal portions and determine the value of the communicated data based on the time delay between them. Signal portions modulated by the modulation code, can be detected by convolving the received signals with the modulation code.
