CORRELATION METHOD OF EMBEDED SYSTEM

摘要

PURPOSE: A correlation method of embedded system is provided to reduce the amount of the memory by reducing the size of a correlation map memory and implanting correlation map memory. CONSTITUTION: In a correlation method of embedded system, a copy signal of a corresponding GPS satellite is generated in a copy generation step(S200). An I-address and Q-address are generated in an address generation step(S300). The I-address is generated by using the copy signal and an I-component of the GPS signal. A Q-address is generated in using the copy signal of the GPS signal and an Q-component of the GPS signal. An I-correlation value and an Q-correlation value are called(S400). An IQ correlation value is generated by combining the I-correlation value and Q- correlation value(S500).
