Method and device for VLC (d,k;m,n;r) coding |
摘要 |
<p>A DSV bit is inserted in an input data string by a DSV bit determining insertion unit. A modulation unit has a conversion table, and the element of the conversion table comprises the element for determining uniquely, and has a conversion rule that residues obtained by dividing the number of "1" in the element of a data string and the number of "1" in the element of a code word string to be converted by 2 are identically 1 or 0 for both residues. A channel bit string is modulated according to the conversion table, and further NRZI modulated by an NRZI modulation unit. Thus, DSV control can be performed with reduced redundancy.</p> |
