Patents by Inventor Yuichi TSUIKI

Yuichi TSUIKI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11336379
    Abstract: A first shift unit (14) that shifts an amplitude value of the I baseband signal and an amplitude value of the Q baseband signal in a lower direction by the predetermined number of bits so that the predetermined number of lower bits thereof have a value after a decimal point, a first rounding unit (15) that rounds-to-even the amplitude value of the I baseband signal and the amplitude value of the Q baseband signal shifted by the first shift unit (14) with a rounding width of 1 in decimal notation, and a first averaging unit (16) that respectively calculates a time average of the amplitude value of the I baseband signal and the amplitude value of the Q baseband signal rounded by the first rounding unit (15) are included.
    Type: Grant

  • Patent number: 10855571
    Abstract: A measurement device and a measurement method capable of performing measurement on a device under test while maintaining a desired high data rate even under poor communication conditions such as occurrence of retransmission of a frame from a device under test in a wireless communication connection are provided. The measurement device includes a reception unit 14 that receives a frame transmitted from a DUT 1, a determination unit 16 that determines whether or not a header of the frame has been normally received by the reception unit 14, an acknowledgment transmission unit 13b that transmits the acknowledgment frame to the DUT 1 when the determination unit 16 determines that the header has been normally received by the reception unit 14; and a measurement unit 17 that performs the measurement on the frame determined by the determination unit 16 that the header has been normally received by the reception unit 14.
