<P>PROBLEM TO BE SOLVED: To provide a spread spectrum signal receiver capable of suppressing deterioration in an integrated correlation value due to superimposition of a navigation message in the case of receiving an L2 signal. <P>SOLUTION: A code clock generating section 30 outputs a first code clock signal on the basis of a clock from a control section and outputs a second code clock signal with a frequency twice that of the first code clock signal synchronously with the first code clock signal. An L2CM code generating section 32 outputs an L2CM code epoch signal and an L2CM code on the basis of control contents from the control section and the first code clock signal. An L2CM interpolation epoch generating section 36 outputs an L2CM interpolation code epoch signal with a period shorter than that of the L2CM code epoch signal on the basis of the L2CM code epoch signal and the second code clock signal. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
