Fig. 2From: Holographic detection of AIS real-time signals based on sparse representationAIS binary sequence and Gaussian baseband waveform: The upper subfigure is the AIS binary sequence and the bottom subfigure is the Gaussian baseband waveform. The x-axis denotes the time in milliseconds, and the y-axis is the normalized amplitude. The figure shows that the hopping edge in the binary sequence corresponds to the bit-0-phase in the Gaussian baseband waveformBack to article page
