PURPOSE:To fit easily the high speed of the system by installing a mode change- over circuit of signal body/parallel connection at a unique word detecting device for a 4-phase PSK and connecting two unique word detecting devices in parallel. CONSTITUTION:The device is provided with the first and second unique word detecting parts UW1 and UW2 to have two systems of detecting circuits for the same phase and the orthogonal phase inside and a circuit DIV to divide the inputted same phase column and the orthogonal phase data column to an even number data row and an odd number data column. The circuit to exchange the data column of one side system of the first unique word detecting part UW1 to the data column of other system of the second unique word detecting part UW2, is installed, the same system of the data column is collected at respective unique word detecting parts and the unique word detecting processing is executed. |
