Synchronization equipment

A synchronization equipment for performing correlation processing between a first known pattern included in a received signal and a second known pattern to detect reception timing of said received signal, said equipment comprising:

• correlation value computing means for computing a correlation value between said first known pattern and said second known pattern;
• reception timing detection means;
• and
• reception window control means for sending a reception time to said correlation value computing means and said reception timing detection means, wherein:
• said correlation value computing means computes said correlation value at every said reception time;
• and
• said reception timing detection means compares said correlation value with a predetermined threshold value, detects a first reception time when said correlation value becomes larger than said predetermined threshold value for a first time and a second reception time when said correlation value has become smaller than said predetermined threshold value for a first time after said first reception time, obtains a mean value of said first reception time and said second reception time, and holds said mean value.

• reception window control means for sending a reception time to said correlation value computing means and said reception timing detection means, wherein:
• said correlation value computing means computes said correlation value at every said reception time;
• and
• said reception timing detection means performs an interpolation operation with respect to said correlation value to obtain an interpolated correlation value, performs a comparison operation to compare said interpolated correlation value and said predetermined threshold value, and determines said reception time when said interpolated correlation value becomes larger than said predetermined threshold value to be a reception timing of said received signal.
