1. for a method for code phase search spread-spectrum signal, wherein said spread-spectrum signal has repetition bits sequence, and described method comprises:

  • Receive the first spread-spectrum signal;

    Form first signal section by the Part I segmentation described the first spread-spectrum signal;

    After forming described first signal section, form secondary signal section by the Part II segmentation described the first spread-spectrum signal;

    Be not more than and form on the required time interval of described secondary signal section at one, all phase delay is partly correlated with first signal section and corresponding the first replica signal segment;

    The Part I correlated results of all phase delays to first signal section is stored in to corresponding memory bit to be set up.
