摘要： Disclosed is a wake-up system based on an oscillation principle adopted to wireless transmission/reception devices such as remote controllers, mobile communication terminals, etc. The wake-up system uses oscillation capable of performing a wake-up operation such that a receiver responds to a wake-up signal transmitted from a transmitter with a relatively low power, as an amplifying unit including an amplifier and a correlator is oscillated, in which the correlator is connected to the amplifier through a positive feedback loop and another correlator having the same structure as that of the receiver is applied to the transmitter.

摘要： Disclosed is a wake-up system with passive correlators, adopted to wireless transmission/reception devices such as remote controllers, mobile communication terminals, etc. The wake-up system includes a transmitter and receiver. In the transmitter wake-up signals and delayed wake-up signals delayed by a predetermined delay time are correlated and coded, respectively, for transmission. In the receiver, signals transmitted from the transmitter and signals delayed by the predetermined delay time are correlated and decoded, respectively. The decoded signals are converted into DC switching voltage VSW for a switching operation of power, thereby performing a wake-up operation. The wake-up system with passive correlators can reduce consumption power for wake-up operations in a receiver such that correlation operations of a correlator including passive electrical elements such as a matched filter, etc. are performed at a transmitter and the receiver in the same fashion and wake-up signals are transformed into a signal for performing the wake-up operation in the receiver.

摘要： The invention relates to a receiver having a digital timing recovery function. The receiver of the invention detects frequency offset of a received signal by using symbol correlation between the received signal and a reference signal, and increases/decreases the number of data samples according to the detected frequency offset, thereby recovering symbol timing of the received signal.
