  • Publication number: 20240287748
    Abstract: A road surface management device 1 includes a deterioration detection unit 2, a deterioration index calculation unit 3, and a display processing unit 4. The deterioration detection unit 2 detects a crack in a road surface on the basis of an image of the road surface acquired from a vehicle. The deterioration index calculation unit 3 calculates, for the detected crack, a crack width and a crack rate on the basis of the image. The display processing unit 4 superimposes the calculated crack width and crack rate on the road surface on a map.

  • Patent number: 9032267
    Abstract: A transmitting unit divides a transmit data into a plurality of code blocks, and encodes each of the plurality of code blocks to generate a transmission signal. The transmitting unit transmits the transmission signal, and a receiving unit receives the transmission signal as a reception signal. The receiving unit, when being an error in the reception signal, transmits a retransmission request feedback data which contains a NACK data and a data indicating the first code block group to the transmitting unit. First resources are assigned for each of the plurality of code blocks of the transmission signal. The transmitting unit assigns resources of the first code block group of the plurality of code blocks of the transmission signal to second resources which are fewer than the first resources, based on the retransmission request feedback data, and retransmits the transmission signal to the receiving unit.

  • Patent number: 8539298
    Abstract: A transmitting unit divides a transmit data into a plurality of code blocks, and encodes each of the plurality of code blocks to generate a transmission signal. The transmitting unit transmits the transmission signal, and a receiving unit receives the transmission signal as a reception signal. The receiving unit receives performs an iterative decoding to each of the plurality of code blocks of the reception signal. The iterative decoding is terminated to a first code block group in which an error has not been detected before a first setting iteration count. The receiving unit, when being an error in the reception signal, transmits a retransmission request feedback data which contains a NACK data and a data indicating the first code block group to the transmitting unit. First resources are assigned for each of the plurality of code blocks of the transmission signal.

  • Publication number: 20120328055
    Abstract: Disclosed is a channel estimation circuit that estimates a channel state of each sub-carrier, transforms the estimated channel state information into a time-domain complex delay profile, suppresses a noise by way of processing the complex delay profile, and transforms the complex delay profile into a frequency domain. The channel estimation circuit makes a judgment on the estimated channel state and carries out masking on a part of the complex delay profile in accordance with the judgment for suppressing the noise.
