摘要： A LEX signal tracking method of continuously tracking a LEX signal is provided. The LEX signal broadcast from a Quasi-Zenith Satellite is demodulated. A weekend approach notification signal Snear is generated based on a time within a week obtained from the demodulated LEX signal. A state of a Long code, which is generated when a code correlation processing is performed, is analyzed. If the analyzed code state is in agreement with a stored 997425th code state, a pulse signal dplus is generated. If the generation of the pulse signal dplus is immediately after the detection of the weekend approach notification signal Snear, the Long code is reset to an initial state.

摘要： An interference wave signal frequency is highly accurate and the interference wave signal is surely removed. A controller of an interference wave signal remover detects the interference wave signal based on a frequency scanning result by an entire-range frequency scanner, and sets a notch filter to attenuate the interference wave signal frequency. A local scan frequency band BWfL of a local frequency scanner is set by having the interference wave signal frequency as its central frequency, and local scan frequencies BINL are set so that frequency bands overlap with each other between adjacent frequency BINA. The local frequency scanner frequency-scans input signals to the notch filter. The controller calculates a frequency error δf of the interference wave signal frequency from the local frequency scanner, corrects the interference wave signal frequency which is from the entire-range frequency scanner by the frequency error δf, and updates the setting of the notch filter.

摘要： A code controller configures a code state at a substantially constant and low storage volume, and at a substantially constant computational processing amount, regardless of which state position a desired code state is present in within the state area of the code states. In one embodiment, a state processor detects the position of a desired code state based on an inputted code phase amount. Based on the detection, state processor performs processing for jumping the code state a predetermined interval, and obtains a specific code state near the code state. The state processor selects the appropriate process from among a process for delaying the code state one state at a time from the obtained code state and a process for transiting the code state one state at a time in the direction opposite the delay direction, transits the code state, and obtains the desired code state.

摘要： A code is provided which outputs a predetermined code enable signal by executing a simple control, depending on a clock signal frequency, with an optimal circuit scale. A multiplexer receives integers which are relatively prime, and outputs either of them to an adder, depending on comparator output signal. The adder adds an integer latched by the register and an integer output by the multiplexer, and outputs the result via a multiplexer to the register. The register latches and outputs the received integer to the comparator with a sampling clock signal frequency. In accordance with a threshold set based on the integers and the number of bits of the adder or the register, the comparator outputs a signal having the High state only when the output integer of the register satisfies the threshold condition. The code outputs this as a code enable signal.

摘要： A code NCO is provided which correctly outputs a predetermined code enable signal by executing a simple control, depending on a frequency of a clock signal, with an optimal circuit scale. A multiplexer 1 receives integers of N and M which are relatively prime, and outputs either of them to an adder 2, depending on an output signal of a comparator 6. The adder 2 adds an integer latched by the register 5 and an integer output by the multiplexer 1, and outputs the result via a multiplexer 4 to the register 5. The register 5 latches and outputs the received integer to the comparator 6 with a frequency fs of a sampling clock signal SCLK. In accordance with a threshold set based on the integers of N and M and the number L of bits of the adder 2 or the register 5, the comparator 6 outputs a signal having the High state only when the output integer of the register 5 satisfies the threshold condition. The code NCO outputs this signal as a code enable signal having a frequency fo.
