专利汇可以提供Detector for reception interference of same channel专利检索,专利查询,专利分析的服务。并且PURPOSE: To shorten a work length needed for statistic processing and to suppress dispersion of the detection result by applying the statistic processing to the reception envelope curve information by means of the logarithm compressed value.
CONSTITUTION: The input r(t) of an A/D converter 2 is equal to the analog level information showing the logarithm compressed value of a reception envelope curve and then converted sequentially into the digital level information rD(t). A maximum value holding circuit 3A and a minimum value holding circuit 3B renew their input values as the new holding values only when the input rD(t) is larger an smaller than the holding value respectively. A subtractor 4 delivers the difference S between both input values rDMAX and rDMIN. A center value detecting circuit 5 supplies the difference S by the timing of a short section pulse T
1 and detects M pieces of center values of the S obtained for each cycle of a detecting section pulse T
2 . An interference ratio arithmetic circuit 6 supplies the center value (m) for each cycle of the pulse T
2 and calculates an electric power ratio D
2 /U
2 between a desired wave and a disturbing wave of the relevant detecting section according to a prescribed equation to deliver it.
