Abstract: A radio frequency receiver which has a timing offset recovering function and a timing offset recovering method are provided to recover the timing offset by moving the location of a determination slot according to the offset of a sample signal generated through the signal sampling. A preprocessor(110) converts a radio frequency signal into a digital signal. A differential operation unit(120) obtains a differentiated signal by multiplying the digital signal by a received digital signal. A correlation unit(130) correlates the differentiated signal with each PN code sequence and sequentially outputs the correlated results. A setting unit(140) sequentially stores the correlation values. A demodulated value estimation unit(150) estimates the PN code sequences based on the symbol of the received signal.

Abstract: An SoC(System on Chip) having a low power mode and an operating method thereof are provided to reduce dynamic and static power consumption by including the low power mode, which cuts off a first clock/power and uses a second clock/power of a lower frequency than the first clock/power. A first regulator(110) supplies first power which is main power of an SoC(100). A first clock generator(120) generates a first clock which is a basic clock for operating the SoC. A first memory(150) stores data inputted/outputting to a CPU(130), a DMA(Direct Memory Access)(140), a peripheral device part(160), and a modem(170). A mode controller(180) operates the SoC in an active, idle, or stop mode according to a state of the SoC. A low power mode controller(190) is operated by a second clock of a lower frequency than the first clock and second power of a lower voltage level than the first power to operate the SoC in the low power mode according to the state of the SoC. The lower power mode controller includes a second regulator(191) for supplying the second power, an operation controller(193), a second memory(192), and a second clock generator(194).
