    摘要: When embedding a signal into a selected subcarrier of a multicarrier downlink waveform of regular data/control signaling, a base station modulates the embedded signal with a different modulation scheme than the other data in the downlink waveform. The base station nulls adjacent subcarriers to minimize interference at a low-power wake-up receiver of an IOE device(s). The IOE device wakes up the low-power wake-up receiver at scheduled times to listen for the signal. For synchronization signals, the IOE device corrects a local clock based on a correlation value of the signal to a predetermined sequence. For wake-up signals, the IOE device correlates whatever is detected at the antenna to a predetermined sequence and compares the correlation value to a predetermined threshold. If the threshold is met, the IOE device registers a wake-up signal and wakes the primary transceiver of the device. If not, the receiver goes back to sleep.

    摘要: A calculation output unit of a digital amplitude modulation device calculates and outputs a protection index of an amplifier based on a combined output signal or an amplitude modulation signal. A first protection unit outputs to a control unit a first control signal to place an entire amplifier unit in an off-controlled state, based on the protection index. A second protection unit outputs, to the control unit, a second control signal to control an upper limit number of amplifier units that can be on-controlled in parallel and a third control signal to on/off control the upper limit number or less or the initial number of the amplifiers. The control unit on/off controls the power amplifiers based on an input sound signal, the first control signal, the second control signal, and the third control signal.

    摘要: According to an embodiment, the modulated signal generating device modulates an input signal and generates an output signal. The modulated signal generating device includes a plurality of amplifiers, a combiner, a determining unit and a control signal generating unit. The plurality of amplifiers connects in parallel with one another and each configures to drive based on a control signal and to generate amplified signals. The combiner configures to combine the amplified signals and to obtain the output signal having a stepwise waveform. The determining unit configures to determine number of amplifiers to be driven based on a value of the input signal in a period shorter than a period of the input signal. The control signal generating unit configures to select zero or more amplifiers to be driven from among the amplifiers, based on the number of amplifiers determined by the determining unit, the value of the input signal, and a fluctuation in the value of the input signal, and to generate the control signal for driving the selected amplifier.
