Anordnung zur Phasenmehrdeutigkeitsauflösung für ein BPSK-Kommunikationssystem

摘要

In the communication system using the binary phase shift keying (BPSK) modulation method, an erroneous data that might be caused by a carrier slip of carrier wave generated during coherent detection can be compensated. The modulation unit of the transmitter transmits identical data at differentiated timing through BPSK modulation, and the coherent detector circuit of the demodulation unit of the receiver detects waves upon receiving signals. The compensating circuit makes time differences in transmitted data equal and compares them to detect mismatch in order to compensate carrier slip found in the received signal and then the combination circuit realizes the combination.
