In the present invention, UW gate signal generator generates a UW gate signal for detecting a unique word. Gate circuit masks received signal using UW gate signal. PN detector compares a preset unique word signal set value and the signal output from inverting circuit during the active-high interval of UW gate signal, detects whether or not they are matching, and outputs the result. UW detector compares a preset unique word signal set value and the signal output from gate circuit during the active-high interval of UW gate signal, and outputs UW detection signal. Error detector outputs a detection stop signal for stopping unique word detection based on the signals output from PN detector and UW detector. |
