ABSTRACT:
A false-synchronization detection device comprises an up-down counter which counts down a predetermined amount of clocks when codes of phase changes at former and latter halves of a symbol interval are different, and counts up a different predetermined amount of clocks, which is less than the previous one, when codes of phase changes at former and latter halves of the symbol interval are the same. Thus, the false-synchronization detection device is capable of recognizing false-synchronization of symbol timing when the count value falls as far as the predetermined value.
