Channel Capacity Analysis of Spread Spectrum Watermarking in Radio Frequency Signals
The carrier of the digital watermark expands from audio signals to radio frequency (RF) signals. Unlike audio signals, RF signals, such as the watermark transmission carrier, must be correctly demodulated with the watermark signals so that the distortion of the digital carrier embedded with the wate...
