A multiplication value decision unit (12) decides a multiplication value which is a positive value or a negative value corresponding to a bit value of each bit contained in a binary bit string constituting a scramble pattern generated in a pattern generation unit (11). A multiplication processing unit (13) multiplies symbol data representing each symbol value in the symbol data string formed by the multinary symbol containing a predetermined pair of a positive value and a negative value having an identical absolute value, in the value area, by the multip...
1. A scrambler for performing a scrambling of symbols, comprising: pattern generation means for generating a scramble pattern for each symbol;multiplication value decision means for determining a positive or negative multiplication value corresponding to a bit value of each bit contained in a binary bit string forming a scramble pattern generated by the pattern generation means;symbol data generation means for inputting a data string whose significance level is predetermined, dividing significant data of the data string to generate high-importance bit da...
