摘要： A time information receiver that receives a standard radio wave containing a time code and analyzes the time code based on a demodulated signal of the standard radio wave includes a falling edge cycle measurement part that measures a falling edge cycle of the demodulated signal over a measurement period set in advance and counts an occurrence in which the falling edge cycle is determined to coincide with any of 400 ms, 700 ms, 1300 ms, and 1600 ms, a low level width measurement part that measures a low level width over the measurement period whenever the falling edge cycle of the demodulated signal occurs and counts an occurrence in which the measured low level width is greater than or equal to a predetermined threshold greater than 300 ms but smaller than 500 ms.

摘要： A system and method for a radio controlled clock receiver adapted to extract timing and time information from a phase modulated signal. The official time signal is broadcast from a central location using a modified modulation scheme, which adds phase modulation over the legacy amplitude modulation, such as the legacy WWVB pulse width modulated (PWM)/amplitude shift keying (ASK) modulation, thereby allowing for improved performance. The information modulated onto the phase contains a known synchronization sequence having good autocorrelation properties, error-correcting coding for the time information and notifications of daylight-saving-time (DST) transitions that are provided months in advance. The modulation scheme is based on a form of phase modulation, such as binary-phase-shift-keying (BPSK) or phase reversal keying (PRK). The reception of multiple frames with repeated or sequential information allows for the accumulation of received energy over multiple frames to provide for a corresponding gain in the receiver.

摘要： A novel and useful multi-antenna receiver that receives, demodulates and decodes a broadcast signal, whose modulation and encoding of time and timing information allow for reliable and power-efficient operation. The multi-antenna receiver of the present invention is adapted to eliminate or substantially reduce the reception nulls that occur in receivers having a single antenna that is placed in a fixed position. Two or more antennas are employed whereby the receiver generates a combined signal based on a combination of the individual antenna signals or selects one of the antenna signals for input to the receiver based on desired criteria such as signal-to-noise-and-interference-ratio (SNIR). This results in greater robustness of the communication link by reducing or eliminating reception nulls and by rejecting interference through the selection of the antenna for which the signal-to-interference ratio is higher. The invention includes various antenna configurations that are adapted to reuse a single core for multiple antennas or to otherwise reduce size and/or cost.

摘要： The receiver (1) is for receiving radio-synchronous signals for adjusting the time base of a timepiece. The receiver includes an antenna (2) for receiving radio-synchronous signals, a low noise amplifier (3), connected to the antenna, a frequency conversion unit (7) for converting the frequency of the filtered and amplified incoming signals from the amplifier, and a processing unit (8) receiving data signals (data_out) from the conversion unit for adjusting the time base. The conversion unit includes a local oscillator stage (10) with a quartz (12) for supplying oscillating signals (Sm) at a determined frequency, a mixer unit (4) for mixing the incoming signals with the oscillating signals from the oscillator stage to generate intermediate signals (IF), a bandpass filter (5) for filtering the intermediate signals (IF), and a demodulator (6) receiving the filtered intermediate signals and supplying the data signals. The local oscillator stage is configured automatically by a control signal (Cm) from the processing unit to adapt the frequency of the oscillating signals (Sm) in accordance with the incoming radio-synchronous signal frequency, so that the intermediate signal (IF) frequency is within the frequency band of the bandpass filter.

摘要： A configurable system and method for a radio controlled clock (RCC) receiver adapted to apply different strategies for extracting timing and time information from a phase modulated signal depending on the type of application the RCC is used in and on the reception conditions. The official time signal is broadcast from a central location using a modulation scheme which includes phase modulation that alternates between different information rates, allowing for multiple alternative reception modes that are suited for different ranges of signal-to-interference-and-noise-ratio (SINR). The operation of the RCC is configured by the application that hosts it, such that the reception performance and the energy consumption best suit that application. The reception mode used by the RCC at a given time may be selected automatically, i.e. without user intervention, based on the device's profile of operation and the reception conditions.
