  • Patent number: 9455822
    Abstract: A transmitter for transmitting a transmission signal subjected to modulation after error correction coding and a receiver including a phase compensation unit for receiving the transmission signal and performing demodulation therefor while maintaining synchronization thereof and an error correction decoding unit for performing decoding processing for received data that has been subjected to the demodulation. The transmitter transmits a signal formed of a plurality of pilot sequences as a part of the transmission signal, and the receiver has a phase slip estimation processing function for estimating the phase slip by the phase compensation unit by using the plurality of pilot sequences, and for estimating a phase difference component by the error correction decoding unit, to thereby correct a phase of the received data.

  • Patent number: 8576319
    Abstract: An image sensor and an image sensing method can obtain image signals with a high S/N ratio in a high-speed image pickup operation. Signal charges are input to input transfer stage 31 of CCD memory 30. Final transfer stage 32 is formed so as to be connected to the input transfer stage 31 and able to transfer signal charges to the input transfer stage 31. In an accumulation mode, read gate 42 and drain gate 40 are not turned on and the next transfer operation of the CCD memory 30 is conducted. The accumulated signal charges are transferred on a stage by stage basis and the signal charges obtained at the first image pickup timing are transferred again straightly to the input transfer stage 31. In this state, the signal charges obtained newly at photoelectric conversion section 20 at the next image pickup timing are injected into the input transfer stage 31 by way of input gate 21.
