Abstract

PURPOSE:To ensure a compensation in accordance with the change of the interference state, by subtracting the value of the memory element selected based on the presumed identification value of the 2nd data from the 1st data and at the same time giving a correction to the memory contents based on the input-output difference of the final identifying circuit. CONSTITUTION:The presumed identification value of the 2nd data obtained by the 2nd polarized wave is produced through preidentifying circuit 1, and one of memory elements 30-33 is selected according to the presumed identification value to be connected to subtractor 20. This selected value is subtracted from the 1st data at subtractor 20, and this result is applied to final identifying circuit 21 to give the presumed identification to the 1st data. Furthermore, the input-output difference of circuit 21 is detected by subtractor 51, and a correction is given to the output of memory circuit 3'' based on the detection value.
