Abstract: |
|||
| This invention relates to a information coding and identification method based on special inversion, which is characterized by the following: the information coding comprises application modulation load signal on information signal; selecting one section according to one time length to record on medium; the information identification comprises medium signal and then applies time length relative modulation load signal for interference modulation; the said modulation load signal and its relative modulation load signal to meet special inversion relationship with crossing. | |||
