  • Patent number: 9735815
    Abstract: To provide a radio apparatus including an amplifier, a first mixer, an analog-to-digital converter, a distortion compensator, and an oscillator. The amplifier amplifies power of a transmission signal. The mixer unit mixes a feedback signal from the amplifier with a local signal of a predetermined frequency. The analog-to-digital converter performs analog-to-digital conversion on an output signal of the mixer unit. The distortion compensator compensates nonlinear distortion of the amplifier based on a digital signal obtained by performing the analog-to-digital conversion. The oscillator changes a frequency of the local signal to be mixed with the feedback signal in the first mixer in a time division manner, with frequency spacing corresponding to a sampling rate of the analog-to-digital converter.

  • Patent number: 8498789
    Abstract: An ECT torque controlling system sets a torque demand amount. The torque demand amount set by the ECT torque controlling system is converted by a converter of a power train manager into a torque demand amount changing with a delay relative to the set torque demand amount. A selector of the power train manager switches between a state of converting the set torque demand amount into the torque demand amount changing with the delay relative to the set target value and a non-conversion state. An engine controlling system controls an engine so as to achieve the torque demand amount.
