Device to calculate correlation value corresponding to frequency error; has 0th stage to correlate between reference and measurement signals and nth stage to determine frequency component signals

摘要

The device (1) has a zeroth stage correlation device (110a) to output a correlation between a reference signal (R(t)) and a measurement signal (S(t)) and an nth stage correlation device (110b,c,n) with a frequency adder to calculate a frequency component addition signal with a frequency component, which is added to the reference signal. The device also has a correlation calculator to output a correlation between the frequency component addition signal and the measurement signal and an adder (120) to add the outputs of the zeroth and nth stages. Independent claims are included for a method for using the device, a computer-readable medium for a program for implementing the method, a correlation system and method, a computer-readable medium for a program for implementing the correlation method and a computer program for implementing the method.
