Abstract
A correlation processing method includes generating a correlation code in which a code value of a chip boundary period is set to a value of a replica code, and a code value of a chip center period other than the chip boundary period is set to a predetermined value, and performing a correlation calculation with respect to the correlation code and a received code signal obtained by demodulating a received signal from a positioning satellite.
Claims6
A correlation processing method, comprising:
- generating a correlation code in which a code value of a chip boundary period is set to a value of a replica code, and a code value of a chip center period other than the chip boundary period is set to a predetermined value;
- and
- performing a correlation calculation with respect to the correlation code and a received code signal obtained by demodulating a received signal from a positioning satellite.
A correlation processing circuit, comprising:
- a correlation code generator generating a correlation code in which a code value of a chip boundary period is set to a value of a replica code, and a code value of a chip center period other than the chip boundary period is set to a predetermined value;
- and
- a correlator performing a correlation calculation with respect to the correlation code and a received code signal obtained by demodulating a received signal from a positioning satellite.
