  • Publication number: 20100098137
    Abstract: An A/D converted and inputted signal is stored in a memory. A sliding correlator sequentially reads the signal stored in the memory and despreads this signal. A despreading timing is adjusted and then the candidate for a despreading code is outputted from a code generation circuit. The despreading code outputted at a predetermined timing is used for obtaining a correlation value of signals outputted from the memory, using the sliding correlator. Thus, by storing signals in the memory, fluctuation of a correlation value caused by fading does not occur while specifying a code or detecting a despreading timing.

The three drive arms are composed of two exciting drive arms (12, 13) that are excited in mutually opposite phases in the reference plane and a non-exciting drive arm (14) located between the two exciting drive arms. Each of the three drive arms has an arm width in a width direction along the reference plane and perpendicular to the first direction. Each of the two detection arms has an arm width greater than that of the drive arm in the width direction, thereby suppressing generation of vibrations along the reference plane.
