  • Patent number: 10523248
    Abstract: A reception device according to an embodiment includes a main terminal, a sub-terminal, a demultiplexer, and a noise reducing unit. To the main terminal, a main signal is input. The main signal includes a broadcast wave. To the sub-terminal, a multiple signal is input. The multiple signal is obtained by multiplex a noise signal and a sub-signal including the broadcast wave. The demultiplexer demultiplexes the noise signal and the sub-signal from the multiple signal input from the sub-terminal. The noise reducing unit reduces a noise component included in the main signal by using the noise signal demultiplexed by the demultiplexer.

  • Patent number: 7489948
    Abstract: A receiver includes an array antenna, terminals, switches, a receiving circuit, a switch control unit and a reactance setting unit. Receiving circuit determines a received frequency and a received signal quality of a received signal by demodulating the received signal provided from the array antenna. The receiving circuit provides the received frequency to the reactance setting unit as a frequency setting signal, and provide the received signal quality to the switch control unit and the reactance setting unit. The reactance setting unit sets a set of the reactances corresponding to the received frequency in the terminals for each frequency, and the switch control unit switches connections in the switches to provide the received signal quality equal to or greater than the threshold.

  • Patent number: 7391386
    Abstract: An array antenna apparatus (100) includes a radiating element (A0) for receiving a transmitted radio signal, two parasitic elements (A1, A2), and two variable reactance elements (12-1, 12-2) connected to the respective parasitic elements (A1, A2), and a directivity characteristic of the array antenna apparatus is changed by changing reactances set to the variable reactance elements. An antenna controller (10) selects and sets one reactance to be set from those in a first case in which a first reactance set is set to the two variable reactance elements (12-1, 12-2) and a second case in which a second reactance set is set to the two variable reactance elements (12-1, 12-2) to be able to obtain a diversity gain equal to or larger than a predetermined value, based on a received radio signal, based on signal quality of the radio signal.
