  • Publication number: 20190165868
    Abstract: Fourier transform is performed on a reception signal to obtain a first calculation value. Fourier transform is performed on a known signal to obtain a second calculation value. The first calculation value is divided by the second calculation value to obtain a third calculation value. Inverse Fourier transform is performed on the third calculation value to obtain a fourth calculation value. A maximum value of an amplitude of the fourth calculation value and a sample point at which the maximum value is obtained are detected. The position of the known signal in the reception signal is detected from the sample point at which the maximum value is obtained.

  • Patent number: 10305675
    Abstract: An FIR filter convolutes sampled data obtained by sampling a reception signal with tap coefficients. A phase difference detector detects a phase difference between a synchronization timing of a signal waveform estimated from an output signal of the FIR filter and a sampling timing of the output signal. A tap coefficient adjuster adjusts the tap coefficients so as to reduce the phase difference detected by the phase difference detector and causes the sampling timing of the output signal of the FIR filter to track the synchronization timing.

  • Publication number: 20190155704
    Abstract: Before an active program replacement is carried out, a storage controller confirms a communication state between a redundant storage controller having a redundant configuration with the storage controller and the second storage device, and prohibits, in a case where an abnormality is detected in the communication state between the redundant storage controller and the second storage device, the active program replacement of the first storage controller. This inhibits occurrence of system down when active firmware replacement process is to be carried out in a storage system including multiple storage devices connected to one another.
