  • Publication number: 20230198577
    Abstract: A method and device for eliminating co-frequency and adjacent frequency interference in an analog domain, in the case that a wireless communication device with a receiving antenna, that is, a transmitting point of a master device, detects and judges the presence of co-frequency and/or adjacent frequency interference signal sources on site, collects the reference signals of the same frequency and/or adjacent frequency from the interference signal sources by means of cable direct connection or adding an antenna, and obtains the analog signals of the same frequency and/or adjacent frequency interference after interference signal recovery processing, then, in the analog domain, the received signal received by the receiving antenna of the master device is directly subtracted from the interference analog signal of the same frequency and/or adjacent frequency to complete the analog interference cancellation process, so as to obtain the interference canceled RF analog signal.

  • Patent number: 8149456
    Abstract: Restriction information on a total colorant amount for a medium is obtained. Patches at grid points in a color space corresponding to a plurality of colorants at which the total colorant amount falls within a restriction represented by the restriction information, and a patch at a point surrounded by the patches are generated. Color values are obtained by measuring the colors of the patches printed on the medium. It is determined based on a color prediction value between the grid points whether the measured color values are appropriate, and if so, a color value at a grid point at which the total colorant amount exceeds the restriction is estimated based on the measured color values. A color separation table is created based on the measured color values and the estimated value.

  • Patent number: 7852511
    Abstract: A color separation table capable of performing both limitation of a color material applied in printing, and suppression of a false contour by smoothing processing satisfactorily is generated. Specifically, after generating the color separation table, smoothing processing is performed in order to obtain conformability between areas constituting the table. So as not to damage smoothness of lattice point data achieved by this smoothing processing, due to landing amount correction processing, landing amount correction is performed for an object lattice point and lattice points in a 3×3×3 range around it.
