  • Publication number: 20160066017
    Abstract: The present technology relates to a reception device, reception method, and program that can prevent erroneous detection of a predetermined signal, such as a P1 signal, included in, for example, a received signal such as DVB-T2. A correlation calculation unit obtains a correlation value between received signals including a predetermined signal in which an original signal and a duplicate signal obtained from a copy of at least a part of the original signal are disposed. An average power calculation unit obtains average power of the received signals. A normalization unit obtains a normalized correlation value obtained by normalizing the correlation value by the average power. The present technology can be applied to a case where a P1 signal being a preamble signal is detected from a received signal such as DVB-T2, for example.

  • Publication number: 20150022263
    Abstract: The present technique relates to a demodulation device, a demodulation method and a program capable of realizing a demodulation process at a rate equivalent to a case where I and Q channel signals are not inverted, even when the I and Q channel signals are inverted. A frequency correction unit establishes synchronization of a frequency and clock based on a signal from a frequency synchronization unit. A channel inversion detection unit of a frame synchronization unit detects presence or absence of inversion of I and Q channel signals, and supplies, as a detection result, a channel inversion detection result to the channel inversion control unit. The channel inversion control unit switches the I and Q channel signals if the inversion has occurred, based on the channel inversion detection result. This technique can be applied to a demodulation device.

  • Patent number: 8418448
    Abstract: An engine (8) is mounted to a vehicle body by means of vibration isolating mounts (8E), and a support member (15) is mounted to the engine (8). Vibration isolating members (20) are provided between this support member (15) and a mounting bracket (17) mounted to an exhaust gas treatment device (16). Accordingly, even in cases where the engine (8) has generated high-frequency vibrations, these vibrations can be damped by the vibration isolating mounts (8E) and the vibration isolating members (20). In consequence, treatment members constituting the exhaust gas treatment device (16), such as a catalyst, a filter, and a sensor, can be protected from the vibrations of the engine (8). In addition, as the exhaust gas treatment device (16) is provided with the mounting bracket (17), the vibration isolating members (20) can be reliably mounted to the exhaust gas treatment device (16) by means of the mounting bracket (17).
