<p>PROBLEM TO BE SOLVED: To reduce an interference in the transmission of a communication signal by storing the communication signal which is received as a fault time function, analyzing an interference signal characteristic so as to recognize a signal type, selecting a restricting method in accordance with the type of the interference signal within the range of a time when the interference signal occurs and obtaining a non-interference communication signal. SOLUTION: A circuit has a memory 1, characteristic detecting equipments 21...2n, circuit blocks 31...3n assigned to the respective characteristic detecting equipments for setting the time range and modules for interference blanking 4, an interpolation 5, a subtraction and reproduction. Then the communication signal received as the fault time function x(k) is stored in the memory 1. The detecting equipments 21...2n analyze the interference signal characteristic, recognize the signal type and set the time ranges 31...3n where the interference signal occurs. Moreover, the restricting method is selected in accordance with the type of the interference signal within the range of the interference signal and the interference signal and the recognized interference signal type are processed in order to obtain the non-interference communication signal y(k+t).</p> |
