发明名称 Code modulation method, code demodulation method, and code detection method
摘要 Carrying out DSV control with a PR(1, 1) while making free distance larger and path memory length shorter. "3x3" states are arranged in a plane defined by a horizontal axis and a vertical axis, with a code 11 being allotted to correspond to rightward transitions along the horizontal axis and a code 00 being allotted to correspond to leftward transitions. A code 01 is allotted to upward transitions along the vertical axis and a code 10 is allotted to correspond to downward transitions. Codes obtained in the case of transitions from a start point taken as one of the states 1, 3, 5 or 7, to the states 1, 3, 5 or 7 taken as end points through the other five states are used as codes after conversion. For example, the codes 01, 01, 11, 00, 10 and 10 are obtained from a transition through state 1, state 4, state 7, state 8, state 7, state 4 and state 1.
