    摘要： Receiver architectures and methods of processing harmonic rich input signals employing harmonic suppression mixers are disclosed herein. The disclosed receivers, mixers, and methods enable a receiver to achieve the advantages of switching mixers while greatly reducing the mixer response to the undesired harmonics. A harmonic mixer can include a plurality of mixers coupled to an input signal. A plurality of phases of a local oscillator signal can be generated from a single local oscillator output. Each of the phases can be used to drive an input of one of the mixers. The mixer outputs can be combined to generate a frequency converted output that has harmonic rejection.

    摘要： [Object] To provide a terminal device capable of efficiently performing communication in a communication system in which a base station device and the terminal device communicate with each other.
    [Solution] A terminal device that communicates with a base station device includes: a higher layer processing unit configured to perform one or more second PDCCH settings through signaling of a higher layer from the base station device; a receiving unit configured to monitor only a common search space and a terminal device-specific search space in a first PDCCH in a case in which the second PDCCH setting is not performed, and monitor a terminal device-specific search space in at least a second PDCCH in a case in which the second PDCCH setting is performed. The first PDCCH is transmitted on a basis of a sub frame defined in accordance with a predetermined number of symbols. The second PDCCH is transmitted on a basis of an extended sub frame of a smaller number of symbols than a number of symbols corresponding to the sub frame, and a resource block set through the second PDCCH setting.
