Fig. 7From: Multiple-Symbol combined differential detection for satellite-based AIS SignalsBER curves of 2 bits MSCDD-PCCD and 3 bits MSCDD-PCCD under different frequency offsets. The decoding performance of 2 bits MSCDD-PCCD and 3 bits MSCDD-PCCD remains unchanged when the frequency offsets of received signals are 0, 0.01R b , 0.10R b , 0.26R b , 0.42R b respectively Back to article page
