A generator of the timing information in the baseband using to the symmetry property of center frequency of the band pass filter where is generated in the baseband for restoring the timing. The said generator consist of a adder where output the signal added the input signal and the output signal of the first finite impulse response filter; the first through third finite impulse response filter where output the signal connected linearly; and a multiplier where output the timing information.
