Fig. 5From: Multiple-Symbol combined differential detection for satellite-based AIS SignalsBER curves of 2 bits MSCDD-PCCD and 3 bits MSCDD-PCCD under different phase shifts. The decoding performance of 2 bits MSCDD-PCCD and 3 bits MSCDD-PCCD remains unchanged when the phase shifts of received signals are 0, \( -\frac{2\pi }{3} \), \( -\frac{\pi }{2} \), \( -\frac{\pi }{6} \), \( \frac{\pi }{6} \), \( \frac{\pi }{2} \), \( \frac{2\pi }{3} \), π Back to article page
