    摘要: Integrated correlation values (I and Q integrated correlation values) between each of I and Q signals obtained from a received signal and a code replica are calculated by a coherent integration process performed by a correlation process circuit section 32. A coherent integration enhancement circuit section converts a phase angle θ of each of the I and Q integrated correlation values (IQ coordinate values) into a double angle, and further integrates the converted I and Q integrated correlation values (IQ coordinate values) to calculate I and Q enhanced integrated correlation values. An incoherent integration circuit section performs an incoherent integration process on the I and Q enhanced integrated correlation values. A coherent integration time T1 of the correlation circuit section is set to be 20 ms or less, and an integration time T2 of the coherent integration enhancement circuit section is set to be longer than 20 ms.
