The present invention generally relates to signal superposing systems, communication devices with such systems, and methods therefor. More particularly, the present invention relates to various signal superposing systems capable of generating outgoing signals through superposing background signals onto input signals from an user of the system in real time. Thus, the user may transmit such superposed signals to a third party while giving an impression that the user is currently in a situation represented by such background signals. The present invention also relates to various methods of generating the outgoing signals by superposing the background signal onto the input signal, methods of replacing noise signals in the outgoing signals by the background signals, and so on. The present invention also relates to various processes of providing such signal superposing systems, various processes of providing communication devices incorporating such systems, and so on.
