Piecewise Linear Noise Modulation (PLNM)
Abstract
We present a modulation technique to embed a binary bitstream within a real-valued Gaussian noise sequence. The modulation produces a sequence which possesses an optimal minimum distance property that promotes accurate detection when the sequence has been exposed to noise. Because the modulated sequence possesses Gaussian properties and has low power, it is difficult for unintended parties to intercept and detect the signal. The technique can be used to hide information in a signal that is then added to a carrier for a variety of applications.
